Preparation of Organic Chelating Agents Modified Bentonite for Mixed Contaminant Removal from Aqueous Solutions
Natural Na-bentonites were modified with an organic chelating agent,sodium diethyldithiocarbamatre (DDTC),to prepare a new adsorbent (DDTC-bentonite) for mixed contaminant (Cu2+,Cd2+ and phenol) removal.The optimal conditions for preparation the DDTC-bentonite were investigated.Moreover,the DDTC-bentonite showed significant adsorption for the mixed contaminant from aqueouss solution.The Langmuir and Freundlich isotherm equations were applied to the data and values of parameters of these isotherm equations were evaluated.
