Abstract

In this paper we report the point of zero charge (pHzpc) of natural magnetite and its adsorptive properties with regard to alkali metal ions. It has been found that pHzpc of freshly ground, untreated magnetite is 6.5, decreasing, after treatment with HCl, to the value of pH 3.8. This discrepancy might be explained as a consequence of possible structure changes on the magnetite surface. Adsorption properties of magnetite with respect to Li+, Na+ and K+ ions in the concentration and pH ranges varying from 0.1 to 1.0 mol·dm−3 and 6.5 to 10, respectively, were examined. For the used chloride media used, the adsorption sequence obtained is Na+>K+>Li+.
