摘要：Iron based Titanium dioxide composites were prepared from beach sand of Cox`s Bazaar, Bangladesh, to monitor their efficiency in removing arsenic from contaminated water by column adsorption filtration method in laboratory condition. It is observed that the prepared Iron based Titanium dioxide composite (ITDO-1 and ITDO-2) can do remove 100% both states of arsenic from the prepared 10 mg L^-1 arsenic solution up to the breakthrough volume (ITDO-1 at 3.1 L and ITDO-2 at 1.9 L, for 4 g of column material) in each case. Adsorbed arsenic is amounted to 4871 mg kg^-1 of composite ITDO-1 and removal efficiency is found 72.46% up to the saturation volume (7.35 L) while the corresponding figure for composite ITDO-2 is 6708 mg kg^-1 of material with an efficiency of 62.92% up to saturation volume (7.5 L). This study also revealed that the residue (ITDO-3) left after the prepared ITDO-1 and ITDO-2, exhibited least performance on removing arsenic.
