采用物种分布图和核磁共振实验研究了五硼酸钾溶液中含硼物种的类型、含量和溶液浓度间关系。研究表明五硼酸钾在稀溶液中几乎全部水解为B(OH)3和B(OH)4-;在较浓溶液中主要物种为B3O3(OH)4-和B(OH)3,而B5O6(OH)4-和[B4O5(OH)42-]的含量较小。核磁共振实验研究给出了B(OH)4-, B3O3(OH)4-和B5O6(OH)4-的生成常数K1, K3, K5,研究得出B5O6(OH)4-含量很少的原因是其解聚为其它类型硼酸根离子。外加离子促进五硼酸根离子的生成,而高温条件促进B5O6(OH)4-发生解聚反应。  相似文献

用合成的水合四硼酸钾和偏硼酸钾晶体,配制一系列溶液,研究了pH与浓度变化的关系,并计算硼酸根离子的摩尔分数-浓度(δ-c)关系图。用拉曼光谱方法研究四硼酸钾和偏硼酸钾溶液,给出其拉曼光谱图,并对各峰进行了归属。研究表明,四硼酸钾溶液中存在的物种主要有[B4O5(OH)4]2-、[B3O3(OH)4]-和[B(OH)4]-,而其它物种所占摩尔分数很小;在偏硼酸钾水溶液中,[B(OH)4]-占绝大多数,有很少量H3BO3、[B4O5(OH)4]2-和[B3O3(OH)4]3-。硼酸盐离子浓度越低,越容易水解为聚合度较低的简单物种。  相似文献

利用牛顿迭代方法计算给出硼酸钾溶液中硼酸根离子的物种分布图。研究给出溶液中硼酸根离子的类型、含量以及各硼酸根离子间相互转化方程式,并简单谈论了温度和浓度对硼酸根离子类型和含量的影响。在五硼酸钾溶液中主要硼酸根离子物种为B3O3(OH)4-,B4O5(OH)42-和B(OH)3,而B5O6(OH)4-含量非常低,可以忽略不计;偏硼酸钾溶液中主要离子为B(OH)4-;在高浓四硼酸钾溶液中主要物种为B3O3(OH)4-,B4O5(OH)42-和B(OH)4-。最后用Otakar和Casteel-Amis经验方程式分别研究了硼酸钾溶液的密度和电导率。  相似文献

根据以往相关的研究报道,综述了含硼水溶液中硼物种的存在形式,及其与总硼浓度、溶液pH值、溶液离子强度、温度、压力等因素的关系。随着总硼浓度的提高,硼氧配阴离子的聚合度加大,在pH值较高或较低时,聚硼离子的含量较少,主要以H3BO3和B(OH)4-的形式存在;同时,指出含硼水溶液存在普遍的过饱和现象,我国含硼盐湖卤水中的硼物种可以用B4O72-的综合统计形式表示。总结了硼酸盐水溶液中各种硼氧配阴离子的FT-IR,Raman和NMR的归属。  相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world's largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.  相似文献
