Since many years, research groups throughout the world paying attention on removal of heavy metals from water. Saline water and fresh water both are consumed in diverse human sectors.Arsenic is a common element that is found in small amounts throughout the environment. Acute and chronic poisoning can result from consuming water that contains arsenic. Acute arsenic poisoning has no distinct symptoms. Weariness, colitis, loss of reflexes, weight loss, weakness, anorexia, gastritis, hair loss, and anorexia are a few of the non-specific symptoms of chronic poisoning. As for the pathogenesis of conditions like cardiovascular disease (CVD), hyperkeratosis, disturbances of the nervous and peripheral vascular systems, hyperpigmentation, circulatory disorders, hepatic and kidney disorders, experimental evidence has linked prolonged arsenic poisoning to these conditions (Hall, 2002) [1].Recent advances for air arsenic removal include using both laboratory-scale and pilot-scale methods, as well as numerical modelling to help interpret pilot-scale results. Utilizing a tiny packed-bed reactor, new sorbents and removal methods for arsenic removal from flue gas are being studied on a lab scale. New sorbents are tested in the reactor system to see if they can arsenic from gas streams. These unique sorbents' capacities are calculated as a function of temperature and gas composition, and the findings are contrasted with those obtained using activated carbons that are readily accessible in the market.
