Abstract: Main factor leading to restricted soil conditioner use of compost is its heavy metal content. This paper deals with the removal of heavy metals from municipal solid waste (MSW) compost using Na₂EDTA and a mixture of Na₂S₂O₅ and Na₂EDTA in the batch mode. At the end of extraction studies, for 3 h at 1:25 solid:liquid ratio by using 0.05 M Na₂EDTA, 100% removal yields were obtained for all metals studied. Further, heavy metal removal ( 100%) were obtained with 0.01 M Na₂EDTA and 0.1 M Na₂S₂O₅, at 1:6 solid:liquid ratio, for all heavy metals of this study.
