Diphenylamine에 의해 표면개질된 역삼투막의 내염소성 및 내오염성 향상
Surface Modification of Reverse Osmosis Membrane with Diphenylamine for Improved Chlorine and Fouling Resistance
(Received October 3, 2013, Revised December 13, 2013, Accepted December 21, 2013)
Abstract
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.
