摘要

•A high permeable PA-based NF membrane was prepared by a controlled CDRIP method.•Membrane structure was optimized by complexing/dissociating processes of TA/Ca(II).•Both the hydrophilicity and surface negative charge of membrane were enhanced.•The PA/TA/Ca(II)-SC NF membrane exhibited high permeability and Na2SO4 rejection.
