Adsorption of Manganese (VII) ions from aqueous solution onto a activated orange peels powder as low cost adsorbent has been investigated. The effects of various parameters such as contact time, initial manganese ion concentration, pH, particle size and adsorbent dose on the removal of Mn(VII) have also been studied systematically. The optimal pH value for Mn(VII) removal by the activated orange peel was found to be 2. The maximum removal efficiency was found 71.3% at pH 2. Equilibrium study was examined by the Langmuir and Freundlich isotherm equations.
