The detrimental impact of presence of arsenic in the environment has an adverse influence on the human beings. In the present research, varieties of biomaterial are being developed to provide a wide platform for the removal of heavy metals and toxic elements. Some of these materials also could remove contaminants and toxicants form the environment. Studies have revealed that preparation of biosorbents is quite cost effective and efficient to remove metal pollutants form aqueous medium. In the present study, an attempt has been made to analyze the biosorption capacity of the biosorbent. The kinetics and adsorption isotherm has been established. It has been found that Langmuir isotherm could fit successfully to the above process and the reaction is found to be fit to first order kinetic model.
