Preparation and characterization of AM-co-APTAC/TiO2 nanocomposite for environmental applications


TiO2 nanoparticles are used as self-cleaning and anti-bacterial agents due to their excellent photo-catalytic activities. An organic–inorganic hybrid is prepared via radical graft polymerization. First, the TiO2 nanoparticle surface was modified by vinyltriacetoxysilane as coupling agent using a sol–gel technique in aqueous media. Afterwards, the modified nanoparticles were copolymerized by 3-acrylamidopropyltrimethyl ammonium chloride and acrylamide monomer in presence of potassium persulfate as initiator. The synthesized nanocomposite was then used for the optimal removal of suspended solids and dyestuff from an industrial wastewater. FTIR spectra proved the connection of polymeric chains onto the surface of the nanoparticles. SEM micrographs along with Ti-map, TGA technique, x-ray diffraction patterns and EDX analysis were used for characterization and properties of nanocomposite. It was clearly shown that in the presence of nanocomposite, the degradation of Rh.B occurred well.
