A β-(1-4) linked polysaccharide (Chitosan) in tripolyphosphate-zinc oxide (CTPP-ZnO) eco-conductive membrane

Abstract

In article, we have reported a β-(1-4) linked polysaccharide as chitosan is crosslinking to tripolyphosphate (TPP) which on impregnated with zinc oxide (ZnO) nanoparticles, formed an ecofreindly chitosan tripolyphosphate - zinc oxide (CTPP-ZnO) membrane film. These CTPP-ZnO membrane act as conductive behavior and serve as a good adsorbent or to improve the antifouling performance in membrane surface. In synthesis of CTPP-ZnO membrane, the concentrations of TPP is being 0.5%, 1.0% and 1.5% about at pH 5.0 with chitosan. Then CTPP is dried over to ZnO at 60 °C until a CTPP-zinc oxide (ZnO) thin film is formed. The membrane performance test have been checked by using of methylene blue pigment dye when 4 ppm concentration is passed through the membrane. The addition of ZnO reported that the interaction of methylene blue and ZnO nanoparticles mainly consider as the ionic bonding between the positively charged of ZnO and negatively charged of methylene blue (-SO3-), which led to affect in hydrophilicity of polyelectrolyte membrane with high performance to reverse transport in osmosis during performance test.
