Removal Soil Lead (Pb) from EDTA Leachate by Bentonite and Modified Bentonite
There is little information about removal soil Pb from EDTA leachate. Modified bentonite was successfully synthesized from original bentonite and iron (Fe) in this study. Removal efficiency of Pb from the EDTA leachate using the modified bentonite was higher than that of original bentonite. The highest removal efficiency of Pb was 65% with modified bentonite with pH 3.0. The results of this work proposed a potential way for removal of soil Pb from the EDTA leachates.
