Abstract:
 Ethylene diamine tetraacetic acid(EDTA) was chosen as the complexing agent to study the enhanced effects of nanofiltration for the removal of lead and copper mixed ions from soil acidic leachate. The effects of pH , concentration of EDTA and applied pressure on ions rejection were examined in complexation nanofiltration, and simultaneously its process conditions were optimized by orthogonal experimental design. The results show that the lead and copper mixed ions rejection and the permeate flux increase obviously with the present of EDTA in nanofiltration process. In addition, this paper obtains the best operating conditions of complexation nanofiltration for removal of lead and copper mixed ions.
