Deepika Haldhar, Sunanda Sahoo, P. C. Mishra
Abstract :
Adsorption has been demonstrated to be a useful alternative to conventional treatment systems for the removal of toxic metals from aqueous solution. In the present study the adsorption of As (III) on groundnut shell was evaluated. Batch adsorption experiments were conducted to find the effect of parameters like adsorbent dose, contact time, pH, temperature and initial metalloid concentration. The maximum adsorption efficiency was found to be 28.5 µg out of 50 µg from the As (III) beå aqueous solution. The removal of the metalloid ions was dependent on the physico-chemical characteristics of the adsorbent and other parameters. The adsorption data were fitted to Langmuir and Freundlich isotherm models. The Langmuir model showed better representation of data, with correlation coefficient greater than 0.98.
