摘要： 采用化学连续浸提法对冶炼厂污染土壤中铜的赋存形态进行了比较分析,并且计算了铜的生物有效性系数.结果表明,铜生产区铜的形态分布(质量分数)顺序为:残渣态>碳酸盐结合态>有机结合态>铁锰氧化物结合态>可溶态、可交换态;而锌生产区铜的形态分布(质量分数)顺序为:残渣态>有机结合态>碳酸盐结合态>铁锰氧化物结合态>可溶态、可交换态;铜主要是以较稳定的残渣态为主,铜生产区达63.4%,锌生产区为38.5%.根据计算铜生产区、锌生产区重金属的生物有效性系数大小顺序分别为:K3>K2>K1,K2>K3>K1.

Abstract: The form of copper occurrence in contaminated soil in a smeltery site was discussed comparatively by continuous chemical digestion, with the coefficient of biologic effectiveness to copper calculated. The results showed that the distributive form of copper in the copper smelting area is in an order of RES>CA>OM>Fe-Mn>EXC and WS, while in the zinc smelting area the distributive form of copper is in an order of RES>OM>CA>Fe-Mn>EXC and WS. It showed that copper is mostly in the form of residue, i.e., the 63.4% in the soil of smelting area and 38.5% in that of zinc smelting area. The biologic effectiveness coefficients to heavy metals in the soil of both areas are in an order of K3>K2>K1, K2>K3>K1 correspondingly as a calculated result.
