Adsorptive Removal of Chromium (VI) from Synthetic Wastewater by Using Chalk powder as Cost Effective Adsorbent

( Volume 3 Issue 7,July 2016 ) OPEN ACCESS

N. Gandhi, D. Sirisha, K.B. Chandra Sekhar


In this study, a series of batch laboratory experiments were conducted in order to investigate the feasibility of chalk powder as cost effective adsorbent for the removal of chromium from aqueous solution by the adsorption process. Investigation was carried out by studying the influence of initial solution pH, adsorbent dosage, contact time and initial concentration of chromium. The particle size of chalk powder used was 250 mic. All batch experiments were carried out at a constant temperature of 30°C (±2°C) using mechanical shaker that operated at 100 rpm. The single component equilibrium data was analyzed using Langmuir, Freundlich and Temkin adsorption isotherms.
