摘要：
A sequential extraction procedure is proposed, in order to fractionate total heavy metal present in sewage sludge particulate into different chemical forms, which can be released from sludge and pass into the leaching solutions. The extracting reagents KNO3, CO2-supersaturated water, sodium ethylenediaminotetracetate solution and dichloromethane were chosen in order to simulate conditions undergone by sludges when disposed to landfill. The metal extracted into the different fractions was evaluated and correlations were proposed between metal mobility and eluting agent properties.
