Abstract
Treatment of wastewater for their metal contents is gaining importance in these days. Amongst the various methods reported in the literature, metal adsorption potential by low cost adsorbents is found to be techno-economically feasible action. Studies carried out to evaluate adsorption potential of low cost adsorbents Rice husk (RH), Saw dust(SD) and Ground nut shell(GS) under varied experimental conditions viz. adsorbent bed depth, particle size of adsorbent are presented in this paper. The sequential order of removal potential was found to be SD>RH>GS. Inverse relationship with removal efficiency and particle size of adsorbents and linear relationship between removal efficiency and bed of the adsorbent has been recorded.
