Due to increase in population coupled with mining, extraction, and use of various metals as different industrial and household materials, the load of toxic metal pollution in the environment is increasing. Toxic metals can be hazardous even at very low concentration. When they get into water supplies and aqueous environments the health of plants and animals as well as humans can be impaired. The demand of chromium has been increasing globally because of its extensive use in various metallurgical, chemical, and leather tanning industries due to its various physico-chemical properties. The adsorption of toxic metals is strongly dependent on pH, temperature, contact time, and initial adsorbate concentration. The studies on adsorption were conducted by varying various parameters such as contact time, amount of adsorbent, temperature, and agitation speed. The increase of adsorbent dose provides more surface area for adsorption hence increased the adsorption capacity of the adsorbent. Agitation speed has little effect on adsorption. Experimental data for the adsorbent was fitted to different isotherm models such as Freundlich and Langmuir isotherm. Langmuir adsorption isotherm was employed in order to evaluate the optimum adsorption capacity of the adsorbent. It was concluded that adsorbent prepared from Peas Shell can be used for removal of Cr(VI) from wastewater. © 2018 by Apple Academic Press, Inc. All rights reserved.
