Abstract

The effect of Fe(III) and Ca as coexistent elements on the extraction of Pb from contaminated soils with the biodegradable chelating agent [S,S]-ethylenediaminedisuccinic acid (EDDS) and the low biodegradable chelating agent ethylenediaminetetraacetic acid (EDTA) was investigated as a series of studies for their applicability for the removal of Pb from contaminated soils by soil washing and electrokinetic processing. The results obtained in this study are summarized as follows:<br> The extraction of Pb with EDTA is suppressed by Ca as coexistent elements at the pH above 7 and by Fe(III) as coexistent elements at acidic region. Meanwhile, the extraction of Pb with EDDS has no effect of Ca at the wide pH range. However, the extraction of Pb with EDDS is significantly suppressed by Fe(III) at the wide pH.<br>
