Arsenic is a normally occurring nephrotoxic metal in natural systems. It is a human carcinogen in water over a wide range of pH values, having harmful effects on human health and environment, even at low concentration. It occurs through a combination of natural processes and human activities. Inorganic As(V) and As(III) are identified to be more toxic than its organic forms. The arsenic is build up through intake of food or contaminated potable water. The largest population in danger is in East Pakistan followed by Asian nation (West Bengal). There is no effective treatment for arsenic toxicity. A great deal of analysis over recent decades has been done to lower the concentration of arsenic in beverage and still there's a necessity to develop low price viable techniques. Existing major arsenic separation technologies such as oxidization, adsorption, precipitation, coagulation and membrane separation. This paper presents the review of current standing of analysis within the space of arsenic removal from contaminated water and comparison of all technologies out there with additional stress on the adsorption. Adsorption has become one of the most commonly used processes. The objective is to do brief study about the removal of arsenic from water by the process of adsorption. The cost of adsorbents developed depends on treatments conditions, availability, processing etc. Cost may vary when the adsorbents are made in developed countries, developing countries and underdeveloped countries. However there are scopes in demonstrating evaluation costs at the industrial scale.
