Arsenic is potentially a carcinogenetic toxic material to human health. The acute lethal dose of arsenic to humans has been estimated to be about 0.6mg/kg/day. Irrespective of various other treatment technologies cerium hydroxylamine can be an efficient adsorbent for removal of Arsenic (III). In the present work, 0.7mg/L adsorbent dose of Cerium Hydroxylamine was treated with Arsenic sample at pH 7.0 in optimum temperature condition of (27±2ºC). The maximum removal of Arsenic found to be 99% as analyzed by AAS (Atomic Adsorption Spectrophotometer). Further characterization includes XRD, FTIR, SEM and EDAX. Batch study are carried out for initial concentration of 10 mg/L, 50 mg/L, 100 mg/L Arsenic (III) using optimum adsorbent dose of 0.7 mg/L having maximum removal 96-99% at pH 2-8 in contact time of 30 minutes with temperature 600C. The synthetic Arsenic concentration was initially 100 ppb. These studies report the result of an extensive investigation pertaining to arsenic removal properties of a hybrid sorbent and produce quality drinking water.
