Adsorption of Iron and Manganese Using Low Cost Materials as Adsorbents

Abstract

Removal of toxic metals (iron and manganese) ions from aqueous solution by adsorption was studied. Batch tests were used to study the removal of each metal either as a single component or both metals as multicomponent. The adsorbents used are low cost materials namely; palm fruit bunch and maize cobs. The adsorption isotherms proved the favor ability of the adsorbent used. Removal of iron ion by adsorption on palm fruit bunch and maize cobs was in the range of 80–57%, and for magnesium ion in the range of 79–50% for initial concentration ranged between 1 and 10 ppm. In case of mixture of both metals, removal of iron from the mixture was in the range 79–54% and for magnesium was in range of 76–54%.
