Kinetic Study of removal Zinc Oxide Nanoparticles from Aqueous Solutions on synthesized CH-g-P(AAc-co-Am)

Abstract

The research contains the preparation of Cross-linking Hydrogel (Chitosan-g-poly (AA - Co - Am)). The way polymerization of the free radicals via utilizing the potassium persulfate as the initiator for the reaction, too with N, N'-methylene bis-acrylamide (NMBA)as a cross-linking agent The mixture gets treated via Acrylamide that includes The adsorption time was 120 mint. The adsorption was proved via utilizing the FESEM and FTIR analysis and analysis TEM And knowing the surface roughness AFM. Also, TGA appears that the hydrogel is stable at high temperatures. The kinetics parameter Study of the Hydrogel was performed via utilizing the Zinc oxide applies to the adsorption from the Pseudo-second order model Because (R2) an approximation of the correct one.
