摘要
采用分步提取法提取污泥样品中的重金属,并采用等离子发射光谱仪测定各态重金属的含量。结果表明,堆肥后多数重金属的形态发生了明显变化,其主要存在形态为比较稳定的残渣态。
The heavy metals in sewage sludge were extracted by step extraction method,and the content of each form of heavy metal was determined by plasma emission spectrometer.The results showed that the heavy metal forms changed obviously in composting,and their main existing form was fairly stable residual form.
