In synthesis of zinc oxide impregnated-chitosan tripolyphosphate (CTPP) polyelectrolyte membrane, the concentration of tripolyphosphate (TPP) may varied, (0.5 %, 1.0 % & 1.5 %) at pH 5.0, with chitosan to zinc oxide nanoparticle ratio is 8: 1, 4: 1 and 2: 1, having specific wider pore radius of CTPP-ZnO membrane. The membrane performance test have applied by using of methylene blue solution with a 4ppm concentration is passed or diffused through the membrane under pressure controlled by valve in 10 bar. Where the addition of zinc oxide reported that the van der Waal’s interaction between functional groups of methylene blue and ZnO nanoparticles mainly consider as the ionic bonding between the positively charged of zinc oxide (Zn (OH) +) and negatively charged of methylene blue (-SO3-), which led to affect in hydrophilicity of polyelectrolyte membrane with high performance as to improve adsorbent or the antifouling performance in membrane surface.
