| Popis: | Water arsenic reduction for human consumption represents a global environmental challenge, and there is a wide variety of methods for its removal. The aim of this study was to investigate the kinetics and equilibrium of arsenic adsorption of a soil from Misiones province, Argentina The material used as adsorbent was a lateritic soil. Kinetics experiments were carried out. Adsorption was evaluated through isotherms, working with concentrations between 0.01 and 30.0 mg As.L−1. Initially, a rapid decrease in the concentration of arsenic was verified, determining an equilibrium time of 24 h. Batch studies results were modeling using Langmuir and Freundlich adsorption models. It was verifying a satisfactory approximation to the Langmuir isotherm, (R[Formula presented].908). The adsorbent studied is considered efficient for arsenic removal and it could be used in isolated areas without potable water. Fil: Boglione Mondino, Rosana de Los Milagros.
