This study investigated the aromatic polyamide reverse osmosis membrane was modified with diphenylamine(DPA) for enhanced chlorine and fouling resistance and how to optimize. DPA has high reactivity and thermo chemicalstability. The performance of a modified membranes was investigated and its surface analyzed using atomic force microscopy(AFM), X-ray photoelectron spectroscopy (XPS) and contact angle measurement. The experiment was conducted whilechanging the conditions of temperature and DPA solution concentration.
