INVESTIGATION ON THE EFFECT OF PARTICLE SIZE AND ADSORPTION KINETICS FOR THE REMOVAL OF Cr(VI) FROM THE AQUEOUS SOLUTIONS USING LOW COST SORBENT.

R. Hema Krishna, A. V. V. S. Swamy.

Abstract
The potential to remove Chromium (VI) from aqueous solutions through sorption using powder of calcined brick (PCB) was investigated using batch tests. The influence of physico-chemical key parameters such as the initial metal ion concentration, agitation time and the particle size of adsorbent have been considered in batch tests. The optimum results were determined at an initial metal ion concentration was10 mg L-1, agitation time – 60 min, and the particle size ( 0.6 mm). The % adsorption, Lagergren rate constant (Kad (min-1)=6.60 x 10-2 for Cr(VI)10 mg L-1) were determined for the adsorption system as a function of sorbate concentration . The kinetic data obtained were fitted to pseudo first order model.

Key words: Adsorption, Cr (VI) ions, powder of calcined brick, Particle size, Adsorption Kinetics, Langmuir Lagergren rate constant
