- Abstract
Mn-Fe binary oxide adsorbents are prepared by co-precipitation method for removal of arsenic from contaminated drinking water. Arsenic adsorption ability is influenced by pH of reaction solution and Mn/Fe mole ratio. Adsorbent M/F4/6-12 with amorphous phase shows higher arsenic removal of 99.9 %. The adsorption isotherm followed Langmuir equation, indicating that it could effectively remove arsenic even from contaminated drinking water in which arsenic concentration is markedly low. The maximal adsorption capacity of As(III) and As(V) are 54.1 mg/g and 49.5 mg/g, respectively.
