The present study comprises the synthesis of polyaniline/Tectona grandis sawdust (PANI/TGSd) composite and its utilization for the adsorptive treatment of synthetically polluted water containing crystal violet (CV) dye. The batch adsorption experiments were carried out to optimize the different experimental parameters such as adsorbent-adsorbate contact time, initial adsorbate concentration, adsorbent dosage, pH and temperature of the medium. The results were analyzed in the light of various isotherm and kinetic models. The isotherm data were observed to be followed well by the Langmuir model, and the maximum monolayer adsorption capacity was found to be 263.2 mg g(-1). The kinetics behinds the adsorption process was found to be best represented by the pseudo-second-order model. The adsorption was thermodynamically spontaneous, endothermic and accompanying with an increase in entropy. The desorption experiments were conducted with some selected media and HCl was observed as the best desorbing agent among HCl, CH3COOH, NaCl, NaOH, and H2O. Results propose that PANI/TGSd is an exceptionally encouraging and efficient adsorbent for the treatment of polluted water containing dyes.
