Abstract

Polyaniline picrate(PANIPI) was synthesized via facile chemical polymerisation route. The as synthesized PANIPI was characterized using UV-Visible, FT-IR and PXRD spectroscopic techniques. Adsorption capacity of the as prepared resin was evaluated from the sorption process. Sorption isotherms were constructed for Langmuir, Freundlich, Redlich-Peterson and Temkin models. The spectral changes after the sorption process were studied using UV-Visible and FT-IR techniques. Facile pH for the adsorption is found to be 5-7. A comparison of ion exchange capacities of PANIPI revealed selectivity of 3:2 for sodium and potassium chloride. The nanosized PANIPI is a potent antimicrobial agent and can be utilized as a biocompatible material.
