Design of chemically treated activated carbon fibers for mercury removal and advanced membranes for water purification
… work, preparation of crosslinked membranes of P84 copolyimide asymmetric membranes using branched polyethylenimine (PEI) at different reaction temperatures was studied. The rejection sequence of CaCl2 > NaCl > Na2SO4 indicated a positively charged membrane surface. Additionally, the resultant …

Design of advanced reverse osmosis and nanofiltration membranes for water purification
Most commercially available reverse osmosis (RO) and nanofiltration (NF) membranes are based on the thin film composite (TFC) aromatic polyamide membranes. However, they have several disadvantages including low resistance to fouling, low chemical and thermal stabilities and limited chlorine …
