The Preparation of Polyarylate Composite Nanofiltration Membrane by Interfacial Polymerization IV Properties and Application of NF 1 Composite Nanofiltration Membrane

Liang Xue

Abstract

The effects of different operation conditions on the separation properties of NF 1 composite nanofiltration membrane were investigated. The stability in solvent and several applications of NF 1 membrane are discussed. The results indicate that the flux of the membrane is 1.99L/m 2 ·h and the rejection of NaCl, Na 2SO 4 is above 90% at the 0.2MPa test pressure.
