Abstract

This study investigates the mutual influence of Mn(II) oxidative crystallization and thallium (Tl) immobilization in nitrate solution under light irradiation. MnOx formed by the photochemical oxidation of Mn(II) effectively removed Tl(I) through adsorption and coprecipitation, with Mn(II) inhibiting the oxidation of Tl(I) to more toxic Tl(III). In turn, Tl(I) suppressed the reductive transformation of δ-MnO2, which favored its own immobilization.
