| Abstract | ||
| This study explained the effect of calcium carbonate on extraction of cadmium from contaminated soil with different extracting agent and surfactant (0.1 M EDTA, 1 M AA, and 1% SDS) (single or mixed extracting agents with surfactant, SDS).The extractedCadmium was more, when 0.1 M EDTAwas used at a pH above 5. Here, the extraction of cadmium from contaminated soil by 0.1 M EDTA decreased with the increase of calcium carbonate content for soil. The extraction of cadmium was moderately effective, when the concentration of acetic acid (AA) was 1.0 M. When the use of 1% SDS alone was ineffective for extraction of cadmium. But, the combination of 1% SDS with 1 M AA was highly effective in the extraction of cadmium. While, the addition 1% SDS to 0.1 M EDTA played only a slight role in the extraction process. | ||
