Manganese dioxide has been tested as an adsorbent for the removal of arsenic using radiometric techniques. Optimum conditions for maximum adsorption in terms of equilibrium time, nature and composition of electrolytes, shaking time, effect of foreign ions and other metal ions have been investigated. On the basis of these data, high separation factor values were obtained in the case of Co II , Hf IV and Te IV . The adsorption data were also found to obey the Freundlich equation, the mean sorption energy of As on MnO 2 being 15.5 kJ/mol.
