研究了工业废水污泥中有毒金属的分布和形态。在这项工作中，修改后的BCR三阶段连续提取程序被施加到分馏的铬铅镍，镉在未经处理的工业废水污泥从工业场地在海得拉巴（巴基斯坦）。提取物采用原子吸收光谱法进行分析。该程序进行了评估，使用认证的参考材料与污水污泥BCR 483混合的土壤。从分区研究的结果表明，更容易动员形式（酸可交换）的镉占主导地位。所有四种有毒金属的可氧化部分占主导地位。金属回收率良好，
The distribution and speciation of toxic metals in industrial wastewater sludge (IWS) was investigated. In this work, the modified BCR three-stage sequential extraction procedure was applied to the fractionation of Cr Pb Ni, and Cd in untreated industrial wastewater sludge from industrial sites in Hyderabad (Pakistan). The extracts were analyzed using electrothermal atomic absorption spectrometry. The procedure was evaluated using a certified reference material for soil mixed with sewage sludge BCR 483. The results from the partitioning study indicate that more easily mobilized forms (acid exchangeable) of Cd were dominant. The oxidizable fraction was dominant for all four toxic metals. Metal recovery was good, with
