| 摘 要： | 以受汞污染的蓟运河水为对象,用化学平衡模拟方法研究了甲基汞不同形态的分布规律,运用IECWDI计算水体系化学平衡程序,收集蓟运河水九种金属离子、十种配体数据,考虑了72种络合物物种,25种可能生成的固体和两个氧化还原体系,计算中需用的甲基汞与黄腐酸络合物常数,建立了溶剂萃取法进行测定。最后计算了盐度、pH、pE等对形态分布的影响。

| Abstract: | The speciation of methylmercury in water sample from Jiyun River contaminated with mercury was studied using a chemical equilibrium model involving 72 complexes and 25 precipitates under two redox conditions. The concentrations of 9 metal ions and 10 ligands in water from the river and the stability constants determined for fulvic acid-methylmercury complexes were collected and IECWDI program was used for the calculation. The effects of salinity, pH and pE on the speciation of methylmercury were also studied. |
