Removal of Cu2+ and Pb2+ Ions Using CMC Based Thermoresponsive Nanocomposite Hydrogel

In this study, carboxymethylcellulose (CMC) based thermoresponsive nanocomposite hydrogel was synthesized for the removal of Cu²⁺ and Pb²⁺ ions from aqueous solutions. To prepare nanocomposite hydrogel, graft copolymerization of N‐isopropyl acrylamide (NIPAm) and acrylic acid (AA) onto CMC was carried out in Na‐montmorillonite (MMT)/water suspension media and ammonium persulfate (APS) used as initiator. The chemical structures of hydrogels were characterized by Fourier transform infrared (FT‐IR) and X‐ray diffraction spectroscopy (XRD). Lower critical solution temperature (LCST), pH responsivity, swelling, and deswelling properties of the hydrogels were also examined. In addition competitive and non‐competitive removal of Cu²⁺ and Pb²⁺ studies were carried out. According to heavy metal sorption studies results, removal capacities of nanocomposite hydrogel for both metal ions were found to be higher than those of pure hydrogel. The analyzed adsorption data showed that the adsorption process of Cu²⁺ and Pb²⁺ could be explained by pseudo‐second order kinetic model. Moreover, according to competitive sorption studies, it is found to be that both hydrogels are more selective to Cu²⁺ ion rather than Pb²⁺.     

太阳活动高年上电离层中O+-H+离子过渡高度的特征

本文用日本电离层探测卫星ISS-b的资料,假设F₂层峰顶以上电离层中各类离子随高度呈扩散平衡分布,得到了太阳活动高年（1978年8月-1979年8月）确定顶外电离层电子密度剖面形状的一个重要参数,即O⁺-H⁺离子过渡高度h_T的一些变化特征.指出h_T的日变化特性主要受电离层中O⁺离子的产生与复合作用的控制.太阳活动高年在不同纬度和所有经度区域,平均说来日间h_T为大约1500-2500km变化,而夜间位于800-1400km,冬夜甚至接近中性氢、氧原子的化学平衡高度.过渡高度也表现出明显的纬度关系,在接近±20°的磁赤道地区,h_T基本上不随纬度变化;但在大于±30°磁纬区域h_T随纬度很快增加.义中还就h_T随时间和地磁（或地理）纬度变化的机制作了简要讨论.

Impact of Ca2+ and Mg2+ on the Removal of F− by Magnesium Potassium Phosphate

This study investigates the influence of Ca²⁺ and Mg²⁺ on the removal of F^? by magnesium potassium phosphate (MPP) from water. The kinetic experiments reveal that the F^? concentration decreased from 3.5 to 3.31 mg L^?1 in a single (F^?) system and to 1.45 mg L^?1 in a ternary system (F^?, Ca²⁺, and Mg²⁺) after 1 min, respectively. Thus, the F^? removal efficiencies are found to increase by about 53% with the co‐active effect of Ca²⁺ and Mg²⁺ in the solution. Moreover, Ca²⁺ and Mg²⁺ are almost completely removed in the F^?, Ca²⁺, and Mg²⁺ system. According to the pseudo‐first‐order modeling, the rate constants k for F^?, Ca²⁺, and Mg²⁺ are 0.00348, 0.0106, and 0.0159 min^?1 respectively; thus, Mg²⁺ > Ca²⁺ > F^?. In the ternary system, the removal efficiencies are 53.29–66.03% for F^?, 99.99–100% for Ca²⁺, and 87.21–95.19% for Mg²⁺ with initial pH 5–10. The removal efficiencies of F^? increases with increases in initial concentrations of F^?, Ca²⁺, and Mg²⁺. The removal of F^? is governed by two routes: 1) adsorption by electrostatic interactions and outer sphere surface complexation; 2) co‐precipitation with Ca₃(PO₄)₂, CaHPO₄, Mg₃(PO₄)₂, and Mg(OH)₂.

Homogeneous Catalytic Ozonation of Lipids Involving Fe2+ and Mn2+: An Experimental and Modeling Study

Given the issue of lipids in effluent treatment systems and their negative impact on the environment, this study aimed to examine lipid degradation by homogenous catalytic ozonation with the aid of iron and manganese ions. This technology presents the possibility of completely mineralizing pollutants using hydroxyl radicals. Milk is chosen as the lipid source because of the high concentration of triglycerides in its matrix, this kind of lipid being the one found most frequently in food and, consequently, in effluent treatment systems. The milk pH value is controlled, and acidic, neutral, and basic conditions are evaluated. The rates of pseudo‐first‐order reactions and the effective value are estimated. It is shown that under acidic conditions low catalyst dosages are enough to cause the complete degradation of lipids. Under neutral conditions, a similar behavior is observed. Under basic conditions, higher catalyst dosages give higher reaction rates. The order of effectiveness of the catalysts under acidic and basic conditions is Fe²⁺ > Mn²⁺, with Mn²⁺ > Fe²⁺ under neutral conditions. Homogeneous catalytic ozonation is therefore efficient at lipid degradation. This technique is viable economically, since the lipid removal occurred at low ozone levels. In addition, the ions used as catalysts are naturally abundant.     

R+ bacteria in estuarine sediments

Increased construction of coastal canal communities had led to a deterioration of the water quality in the canals. In addition to being used for recreational activities, the canals serve as a dumping place for domestic sewage from these communities. This study was conducted to determine the prevalence of transferable drug-resistant (R⁺) bacteria in six coastal canals. A significantly higher number of R⁺ bacteria (both pathogenic and nonpathogenic) occurred in the bottom sediments than in the overlaying water. These sediments can be resuspended following rain, dredging, storms, boating, and diving, thus releasing their bacterial populations into the overlaying water.

Spectrophotometric Determination of Cationic Surfactants Based on Their Effect on the Complexes of Chrome Azurol S with Be2+ and Al3+ Cations

Simple, rapid, and sensitive spectrophotometric methods have been proposed for the determination of cationic surfactants (CS) as cetyltrimethylammonium bromide (CTAB), dodecyltrimethylammonium (DTAB), and cetylpyridinium bromide (CPB). The methods are based on the effects of CSs on the complexes of Al³⁺ and Be²⁺ with Chrome Azurol S (CAS). The optimum reaction conditions such as CAS concentration, metal ion concentration, and pH have been studied and found to be 2.0 × 10^?4 mol L^?1 CAS, 0.5 mg L^?1 Al³⁺ or 0.4 mg L^?1 Be²⁺ and pH 5.4. The analytical characteristics of the methods such as limit of detections, limit of quantifications, and linear ranges have been obtained. CTAB, CPB, and DTAB could be determined by the Al–CAS complex in the ranges of 0.50–40.00, 0.20–10.00, and 0.40–10.00 µmol L^?1, and for the Be–CAS complex in the ranges of 0.08–5.00, 0.08–3.00, and 0.20–6.00 µmol L^?1, respectively. The limit of the detections of the method for the determination of CTAB, CPB, and DTAB for the Be–CAS complex has been found as 0.025, 0.024, and 0.061 µmol L^?1, respectively. The interfering effect of some anions and cations was also tested. The method was applied to the determination of CS CTAB in conditioner shampoo and water samples.     

Influence of the crystal field effect on chemical transport in Earth's mantle: Cr3+ and Ga3+ diffusion in periclase

Experiments were performed to determine concentration-dependent diffusion coefficients of Cr³⁺ and Ga³⁺ in periclase at temperatures of 1563–2273 K. Diffusion profiles measured in the quenched samples are consistent with a theoretical model in which the mobile species is a bound M³⁺-vacancy pair, and each profile was fitted to determine the binding energy and diffusion coefficient of the pair. Trivalent chromium-vacancy pairs diffuse more slowly than Ga³⁺-vacancy pairs, and with higher migration energy, 237 kJ/mol vs. 190 kJ/mol. Cation vacancies also bind less tightly to Cr³⁺ than to Ga³⁺, with average binding free energies of ?22 and ?83 kJ/mol, respectively. At all concentrations and temperatures, Cr³⁺ diffuses much more slowly than Ga³⁺, by up to two orders of magnitude. The differences between Cr³⁺ and Ga³⁺ cannot be explained by differences in ionic radius or dipole polarizability, but are consistent with the influence of the crystal field on the partially occupied 3d orbitals of Cr³⁺. The crystal field splitting stabilizes Cr³⁺ on the octahedral cation site, increasing the energy required for Cr³⁺ to exchange positions with an adjacent vacancy. It also makes Cr³⁺-vacancy pairs less favorable, with the presence of a nearest-neighbor vacancy disrupting the symmetry of the octahedral site, thus diminishing the crystal field stabilization. Trends in the diffusion of first-row divalent transition metals in periclase can also be explained by the crystal field effect. High-spin to low-spin transitions in Fe²⁺, Co²⁺ or Mn²⁺ would significantly enhance their crystal field stabilization in periclase, and if such spin transitions occur in the deep mantle, they would be expected to slow the diffusivity of these ions significantly, perhaps by several orders of magnitude.

为将捞取的微囊藻水华资源化,用作重金属生物吸附剂,本文研究了在不同金属离子浓度和不同pH条件下微囊藻水华对重金属Cu²⁺、Cd²⁺和Ni²⁺的吸附效果.研究结果显示,重金属离子浓度分别为20.00、60.00、100.00和140.00μg/ml时,150 mg干重微囊藻水华对Cu²⁺的去除率分别为67.79%、37.47%、35.93%和34.70%,对Cd²⁺的去除率分别为73.31%、65.87%、60.09%和42.37%,对Ni²⁺的去除率分别为47.89%、31.87%、28.46%和21.61%.在较低的重金属浓度(20.00μg/ml)下,微囊藻对3种重金属的去除率最高.但从单位微囊藻生物量吸附重金属量来看,金属离子初始浓度越高,吸附重金属的总量越高;在相同金属浓度下,微囊藻水华对3种金属的吸附效率:Cd²⁺ > Cu²⁺ > Ni²⁺.微囊藻吸附Cu²⁺的最适pH为5.0,Cd²⁺和Ni²⁺均为6.0,20.00μg/ml浓度时去除率分别达到了71.90%、85.67%和55.43%.微囊藻裂解释放的可溶性物质对重金属吸附影响不大.研究结果显示微囊藻水华可作为重金属吸附剂有效地运用于重金属污水处理.     

La radiazione del sole + cielo a Locarno-Monti

Summary The total radiation from sun and sky upon a horizontal surface is one of the most important elements of climatology. Since 1938 recordings have been made at Locarno-Monti with the Bimetall-Aktinograph Fuess-Robitzsch. In the present publication measurements are elaborated with that instrument, extending over ten years. A comparison of the radiations of the southside of the Swiss Alps with those of the north of Switzerland and in the high Alps shows impressively the extremly favourable conditions of the southern regions: the radiation of Locarno-Monti is very similar to that of the high regions of the Alps and is quite superior to that of the lower parts of northern Switzerland, especially in winter, spring and autumn.

Zusammenfassung Die Strahlung von Sonne + Himmel auf die horizontale Fläche ist eines der wichtigsten Elemente des Strahlungsklimas. Seit dem Jahre 1938 ist in Locarno-Monti ein Bimetallaktinograph Fuess-Robitzsch in Betrieb. In der vorliegenden Publikation sind zehnjährige Registrierungen mit diesem Instrument verarbeitet worden. Der Vergleich des Strahlungsklimas auf der Südseite der schweizer Alpen mit jenem im schweizerischen Mittelland und im Hochgebirge zeigt eindrücklich die ausserordentlich günstigen Verhältnisse der südlichen Region: das Strahlungsklima von Locarno-Monti hat grosse Aehnlichkeit mit dem des Hochgebirges und ist dem Klima in den Niederungen der Nordschweiz, vor allem im Winter Frühling und Herbst weit überlegen.

Résumé Le rayonnement global du soleil et du ciel sur une surface horizontale est un des éléments les plus importants du climat de rayonnement. Un actionographe bimétallique Fuess-Robitzsch fonctionne depuis 1938 à Locarno-Monti. La présente étude se base sur le dépouillement de 10 années d'observations faites à l'aide de cet instrument. La comparaison du climat radiatif au Sud des Alpes avec celui du Plateau suisse et de la haute montagne met nettement en évidence les conditions extrêmement favorables de la région sud-alpine; le climat radiatif de Locarno-Monti présente une grande analogie avec celui de la haute montagne, et se révèle bien supérieur à celui des régions basses du Nord de la Suisse, surtout en hiver, au printemps et en automne.
