Abstract

The studies have been conducted on the removal of the basic dyes Acid Blue 158 and Acid Orange 74 using porous polymeric Amberlite as an adsorbent. The adsorbent was characterized by measuring their porosities and pore size distributions. The microstructure of the adsorbent was examined by scanning electron microscopy (SEM). The batch adsorption experiments were carried out under various operating parameters like initial dye concentration, contact time, adsorbent dose and pH. The equilibrium data fitted well to the Langmuir and Freundlich isotherm equations. The experimental data fitted very well with pseudo second order kinetic model and Elcovich model suggesting chemisorption which is confirmed by desorption studies.
