Preparation and Characterization of Poly (Anilinco-Anthranilic Acid)/Kaolinite Composite and Use It in Removal of CU (II) and CD (II)

Abstract

Copolymers of aniline and o-anthranilic acid (PANAA)/ kaolinite clay composites were synthesized by 5:1 molar ratios of the respective monomers with different percentages of kaolinite clay particles via in situ chemical co-polymerization. The spectral characteristics of the resulting copolymers were investigated. The composite was characteristic by measuring the UV-Vis, FT-IR,TGA , and SEM .Chemically synthesized polyaniline-anthranilic acid/kaolinite (PANAA/kaolinite) composites were used as adsorbent materials for the removal of Cu (II) and Cd (II) from aqueous solutions. The effects of initial kaolinite concentration, temperature, pH, adsorbent dose and contact time parameters onto the adsorption of cadmium and copper ions from aqueous solutions were investigated.
