Abstract

The primary objective of this study is to synthesize polymeric adsorbents and assess the analytical effectiveness of novel organic composites using the batch mode of adsorption. Hence, the organic polymers were prepared by doping the Schiff bases on polyaniline chloride by chemical oxidation method. The prepared polymeric composites were characterized using UV-visible, FT-IR and 1H NMR  spectral techniques. An attempt was made to investigate adsorption capacity of synthesized polymers for the removal of mercuric ion  by varying the various factors such as initial concentration of adsorbates, temperature, contact time, pH, concentration of adsorbents.  Sorption isotherms were constructed using Langmuir, Freundlich, Dubinin Radush Kevich, Temkin and Redlich Peterson models. The  SEM micrograph and PXRD spectra were also recorded to confirm the metal ion adsorption on the surface of investigated composites.
