amino functionalized zno nanoparticles were incorporated to a polycarbonate/polyvinyl alcohol thin film membrane to improve water treatment

Incorporating functionalized zno nanoparticles with amine groups into a thin film nanocomposite (tfn) membrane. polyvinyl alcohol (pva)/zno-nh2 solution was applied to polycarbonate (pc) membranes using the dip-coating method. in a submerged membrane system operating at vacuum transmembrane pressure(tmp), all manufactured membranes were used to remove humic acid [1]. tfn membranes hydrophilicity and surface roughness increased as a result of the inclusion of nanoparticles. as a consequence, for tfc and tfn with 0.05 wt% of nanoparticles, respectively, rejection of ha increased slightly from 98.3 percent to 99.1 percent and 98.3 percent to 99.3 percent when vacuum tmp raised from 0.3 to 0.6 bar
