This paper deals with the eco-friendly and low cost recent techniques of removal of arsenic from aqueous medium keeping in mind the health hazards of arsenic contamination.
Arsenic contamination in ground water of the Gangetic plain in Holocene newer alluvial due to arsenic bearing chemicals has become a matter of grave concern. As a result researches on arsenic mitigation using natural resources are going on in different parts of the world. Natural resources e.g. bentonite mineral of Rajmahal hills and aquatic plants have been utilized for removal of arsenic from aqueous medium. Aquatic plants remove arsenic through their roots and leaves known as phytoremediation and dried biomass is also useful for removal of arsenic known as bio-remediation. The presence of unsaturated carboxylic acid, hemicellulose and amino groups present on the surface of the biomass bind arsenic on the surface but bentonite mineral removes arsenic by adsorption and ion exchange both due to the presence of unsatisfied charges on the surface. Percentage removal of arsenic with varying time by bentonites and aquatic plants have been calculated and experimental data have been used to explain the nature of adsorption.
