Abstract
ADSORPTION CAPACITY OF EGGSHELL POWDER FOR THE REMOVAL OF COPPER FROM SIMULATED WATER AND WASTEWATERS

Dr. P.P. Vishwakarma*

ABSTRACT

The efficiency and Characteristics of eggshell powder were investigated as a low-cost adsorbent for the removal of different heavy metal ions from aqueous solution. Potential of eggshell powder indicates that it is an effective adsorbent, due to high concentrations of carbon and calcium and high porosity and availability of functional groups. Adsorption experiments were studied with varying pH, contact time, and adsorbate concentration. Maximum percentages of heavy metal ions removal were recorded at optimum pH, contact time and adsorbent dose. Determination of the isotherms and kinetics confirmed that eggshell powder has high value of adsorption capacity. This experiment demonstrated the ability of eggshell powder as an effective, sustainable, and low-cost adsorbent for removal of the heavy metal ions in different wastewaters.

Keywords: Adsorption capacity, Eggshell Power, Heavy metals, simulated water, pH.
