摘要
Solidification is a common practice for the treatment of wastes containing heavy metals before they can be disposed of in a landfill. In order to evaluate the suitability of the solidified waste for landfilling, the multiple toxicity characteristic leaching procedure (MTCLP) was introduced to study the long-term leachability of solidified wastes. To this end, an untreated and two cement-based solidified mercury-containing wastes were evaluated by the MTCLP to simulate the long-term leaching behavior of heavy metal contaminants of these wastes in an improperly designed sanitary landfill. The multiple toxicity characteristic leaching procedure is designed by combining the multiple extraction procedure and the toxicity characteristic leaching procedure, which are being used by the US EPA. This paper presents and discusses the experimental procedures of the MTCLP as well as the results of the chemical analysis of leachates obtained from the MTCLP of these wastes.
