Natural husks as potential adsorbents for uptake of heavy metals
Prashant Pandey, Vipin Kumar Saini
The naturally available materials are the sustainable choice for the adsorptive removal of various pollutants from wastewater. The disposal and management of agricultural wastes have been the concern of socio-economic and environmental importance. Hence, agricultural wastes especially husks (originated from rice, peanuts, coconut, black gram, etc.) have been frequently used as anatural source for activated carbon. Studies confirm that husks based adsorbents (either modified or unmodified) have reasonable adsorption potential for uptake of metal ions from wastewater. However, there is still a need to find out the practical utility of such developed adsorbents on a commercial scale, leading to better materials for adsorptive removal applications. In this context, this chapter is intended to review the role of husks as adsorbent development, particularly for heavy metals removal.
