This study investigates the reactivity and removal kinetics of arsenite on single and mixed mineral systems from aqueous solution related to contaminated water in sulfidic-anoxic condition. The sorbents used were zinc sulfide, kaolinite, montmorillonite, and goethite. Using empirical models derived from Freundlich isotherm model, reactivity and sorption kinetics were studied at room temperature (23 ± 2 °C). Reactivity studies demonstrate a proton coefficient greater than one for arsenite sorbed on zinc sulfide and goethite-montmorillonite. Three phase reaction kinetics attributed to outer sphere complexation, inner sphere complexation, and intra-particle diffusion have been suggested. This means that the presence of zinc sulfide under sulfidic-anoxic condition influences the behaviour of arsenite sorption.
