Abstract

Toxics metals have been excessively released into the environment due to rapid industrialization and have created a major global concern. Cadmium, zinc, copper, nickel, lead, mercury and chromium are often detected in industrial wastewaters. Various methods available in literature but due economical point view are facing difficulties to be adopted. Some alternative methods like adsorption material bagasse, rice husk, wheat husk sawdust etc, are more popular due to efficiency as well as cost of treatment. In present study bagasse from sugarcane industry were used to remove the toxic metal from waste. Batch studies were performed to evaluate the adsorption process, and it was found that the bagasse was found to adsorb 96.4% of Cadmium (II) and 93.8% of iron (II). The rate of adsorption follows pseudo-second-order kinetics before attaining equilibrium. The desorption studies suggested that the desorption of Cadmium (II) and iron (II) was the most difficult and the desorption was zero. This work proved that bagasse can be used as an efficient adsorbent material for removal of heavy metals from water and wastewater.
