摘要

Abstract

A low operating pressure nanofiltration membrane is prepared by interfacial polymerization between

-phenylenediamine (MPDA) and trimesoyl chloride (TMC) using PVC hollow fiber membrane as supporting. A series of PVC nanofiltration membranes with different molecular weight cutoff (MWCO) can be obtained by controlling preparation conditions. Chemical and morphological characterization of the membrane surface was carried out by FTIR-ATR and SEM. MWCO was characterized by filtration experiments. The preparation conditions were investigated in detail. At the optimized conditions (40 min air-dried time

aqueous phase containing 0.5% MPDA

0.05% SDS and 0.6% acid absorbent

oil phase containing 0.3% TMC

and 1 min reaction time)

under 0.3 MPa

water flux of the gained nanofiltration membrane reaches 17.8 L/m

⋅h

and the rejection rates of methyl orange and MgSO4 are more than 90% and 60%

respectively.
