Özet
Compost can be used as a soil conditioner as it contains major plant nutrients, such as N, P, and K, microplant nutrients such as Cu, Fe, and Zn, and organic matter, which improves the physical properties in order to have a better soil aeration and water holding capacity. The presence of organic and inorganic contaminants in compost may, however, constitute a danger to the environment. It is the heavy metal content which is the main factor leading to restricted agricultural use of compost. Literature on the effect of compost use on heavy metal levels in the environment shows it to vary according to soil type, plant species and compost quality. This paper deals with the removal of copper from Municipal Solid Waste (MSW) compost using Na2EDTA solution and a mixture of Na2S2O5 (sodium metabisulfite) solution and Na2EDTA solution in the batch mode. At the end of extraction studies, for 3 hours at 1:25 solid:liquid ratio by using 0.05 M Na2EDTA solution, 100% removal yield was obtained for Cu. 100% heavy metal removal yield was obtained with 0.01 M Na2EDTA and 0.1 M Na2S2O5, at 1:6 solid:liquid ratio, for Cu in this study.
