Synthesis and Characterization ofa HybridNanocomposite for Removal of Suspended Solids from Industrial Wastewater

Due to excellent properties of TiO2 nanoparticles and polyelectrolytes for pollutant removal from wastewater, synthesis of a hybrid nanocompositeby sol-gel techniquewas investigated. First,TiO2nanoparticle surface wasmodified by triethoxyvinylsilane (TEVS) as coupling agent. Afterwards, the modified nanoparticleswere copolymerized by 3- acrylamidopropyltrimethyl ammonium chloride (APTAC) and acrylamidemonomers in presence of potassium persulfate initiator during a free radical polymerization.The synthesizednanocompositewas then used for the optimal removal of suspended solids from an industrial wastewater.FTIR spectra provedthe connection of coupling agent group and chains of polymers onto the surface of the nanoparticles. SEM micrographs along with Ti-map showed no sign of eitherphase separation or agglomeration. An efficient removal of suspended solids from an industrial wastewater was also demonstrated by the hybrid nanocomposite
