Abstract

Abstract: Positively charged nanofiltration membranes often exhibit excellent antibacterial and antifouling properties. Nanofiltration membranes with high solvent resistance also find special applications in industrial waste water separation. Cellulose acetate is used to prepare various separation membranes due to its comprehensive performance. LSCF (La0.6 Sr0.4 Co0.2 Fe0.8 O3 ), a kind of cathode and electrolyte material, shows good conductivity in water solution. The nanosized hydrophilic inorganic additive LSCF is added to the casting solution to improve the performance of cellulose acetate nanofiltration membranes. After reaction with glutaraldehyde and trichloro dihydroxypropyl trimethylammonium chloride (TTAC), the prepared membrane demonstrates positively charged characteristics and excellent solvent resistance. Abstract : For a broader application of nanofiltration (NF) membranes, the development of positively charged and solvent‐resistant membranes by a simple method seems highly important. The nanosized hydrophilic inorganic additive LSCF was added to the casting solution to improve the performance of cellulose acetate NF membranes which exhibit positively charged characteristics and excellent solvent resistance.
