Abstract
As(V) oxyanions removal from aqueous systems by dissolved air flotation (DAF) using Fe2O3 · xH2O as solid support and sodium laurate as anionic surfactant was investigated. The influencing factors of the process: pH, support, surfactant, and As(V) concentrations, the presence of flocculant and foreign ions, conditioning time and dissolved air pressure were discussed, as they may affect in a great extent the separation efficiency. The systematic study aims to establish the optimum operating parameters of the process, to investigate the equilibrium and mechanism of separation. [ABSTRACT FROM AUTHOR]
