Abstract
A hybrid method incorporating selective polymeric binding and membrane separation was used for the removal of arsenic from contaminated grou ndwater. Two types of polymers, polyethylenimine (PEI) and poly-dially l dimethyl ammonium chloride (DADMAC) and an ultrafiltration membrane were used at various concentrations and pH. Bench-scale tests demonstr ated a high degree of arsenic removal. The retention of arsenic was al so determined in the presence of various background salts such as NaCl , NaNO3, Na2SO4, Na2CO3. Retention was found to depend on the concentr ation and type of anion present in solution.
