Comparison of As (III) Adsorption Capacity in Aqueous Solution with Iron Nano Oxide and Nano Absorber BACI-2017

Arsenic, one of the elements having most terrible impact on the human being, is threatening the world continuously. It exists in the combined form in rocks under earth which on dissolution contaminates ground water. By various mean, such as industrial activities, it can enter into vital ecological cycle and cause hazards to human health. In the previous paper, it is shown that use of activated carbons such as BACI-2017 can assist in removing As (III) at highest level of 455 mg/g from contaminated water. In this study, the removal of arsenic (III) is compared when different level of nano iron oxides are present. In order to determine the optimal extraction of As (III) in presence of nano iron oxide solutions containing different arsenic concentrations, 5 to 400 mg/l with nano iron particles of 0.5 to 0.1g have been used. BACI-2017 with particle sizes, mesh 4x8 and 100 or higher been also employed. The separation of As (III) was carried out using 0.1 gram of BACI-2017. The maximum As (III) extraction in presence of nano iron oxide and combined nano iron oxide with BACI-2017 are shown to be 19.47 mg/g and 99.36 mg/g respectively during 15 minutes contact times
