有机物对苏州河、黄浦江重金属离子迁移的影响

Effects of Organic Materials on Heavy Metal Ions Transition in Huangpu River and SuzhouRiver

本文根据实验室模拟结果,从理论上解释了苏州河、黄浦江重金属离子迁移规律的二个问题。吸附实验表明大量有机物的存在,与重金属离子形成络合物而抑制了重金属离子进入固相。所以苏州河底泥对重金属的富集系数小于黄浦江。另外,光解实验表明有机物对Cu(Ⅱ)的络合能力远大于对Zn(Ⅱ)的络合能力。故黄浦江和苏州河底泥对重金属的相对富集系数以Zn(Ⅱ)为最小。

Two questions on transition of heavy metal ions in Huangpu River and Suzhou River are theoretically explained. The adsorptional experiments show the organic materials of high concentration to restrain heavy metal ions into sediment so that rich coefficients of heavy metal in Suzhou River are less than in Huangpu River. The photolysis experiments show that the oomplex capability of organic materials with Cu^(++) is more than Zn^(++).
