Determination of cadmium(II), copper(II), manganese(II) and nickel(II) species in Antarctic seawater with complexing resins

The strong species of cadmium(II), copper(II), manganese(II) and nickel(II) in an Antarctic seawater sample are investigated by a method based on the sorption of metal ions on complexing resins. The resins compete with the ligands present in the sample to combine with the metal ions. Two resins with different adsorbing strengths were used. Very stable metal complexes were investigated with the strong sorbent Chelex 100 and weaker species with the less strong resin, Amberlite CG-50. Strong species were detected for three of the considered metal ions, but not for Mn(II). Cu(II) is completely linked to species with a side reaction coefficient as high as log α_M(I) = 11.6 at pH = 7.3. The ligand concentration was found to be similar to that of the metal ion, and the conditional stability constant was around 10²⁰ M^− 1. In the considered sample, only a fraction of the metal ions Cd(II) and Ni(II) is bound to the strong ligands, with side reaction coefficients equal to log α_M(I) = 5.5 and 6.5 at pH = 7.3 for Cd(II) and Ni(II), respectively. These findings were confirmed by the test with the weaker sorbent Amberlite CG-50. It can be calculated from the sorption equilibria that neither Mn(II) nor Ni(II) is adsorbed on Amberlite CG-50 under the considered conditions and, in fact, only a negligible fraction of Mn(II) and Ni(II) was adsorbed. A noticeable fraction of Cd(II) was adsorbed on Amberlite CG-50, meaning that cadmium(II) is partially linked to weak ligands, possibly chloride, while no copper(II) was adsorbed on this resin, confirming that copper(II) is only combined in strong species. These results are similar, but not identical, to those obtained for other seawater samples examined in previous investigations.     

山东全新世滨海软土与工程地质灾害的研究

山东全新世滨海软土分布在海湾、泻湖、河口区，厚度１－１０ｍ。海湾、泻湖软土为淤泥、淤泥质土，陆源物质供应丰富的浅水区，软土颗粒偏粗，强度相对较高，触变性对建筑物危害性大，陆源物质供应少的深水区，软土颗粒偏细，低强度、高压缩性、沉降变形大和蠕变性是危及建筑物稳定的主要因素。海湾、泻湖软土位于地下水位下，具低透水性，掩埋后短期不易排水固结，软土下为强度较高的冲积物，对一般建筑物，利用强夯、粉喷搅拌桩、

波浪底摩擦力对重砂富集的影响——以鲁南近岸区为例

根据浅水波浪的底摩擦效应，对鲁南灵山湾和臼－岚山镇近岸区进行了波浪的海底摩擦力计算。波浪的海底摩擦力等值图与已知滨海锆石砂矿资料对比表明，底摩擦力大于０．１８Ｎ／ｍ＾２的动力分选区有利于重矿物砂富集。据此，进一步预测了鲁南近岸带的砂矿富集区。
