Paper Title:
Preparation and Characterization of Positively Charged Quaternized Chitosan/PEI Composite Nanofiltration Membranes
  Abstract

2-Hydroxypropyltrimethyl ammonium chloride chitosan (HACC) with positively charged character was utilized to fabricate the functional layer of the composite NF membrane and reinforced polyetherimide (PEI) ultrafiltration (UF) membrane was used as the support layer. When the composite membrane was prepared under optimized conditions and tested at 0.4 MPa and 10 oC, the flux of the composite NF membrane was about 18 L/m2h and the MgCl2 rejection of it was about 81.6%. The composite membrane showed classical positively charged membrane character which had higher rejection to high valent inorganic salts.
