Abstract:The process of sulfide precipitation of arsenic in sulfuric acid solution was investigated by observing the changes of oxidation-reduction potential in solution. It was also investigated that the magnetic field affected the potential changes and the content of arsenic in solution during the process of arsenic precipitation, in addition the function of magnetic field effect was examined. It was concluded that the magnetic field effect is beneficial to the rate of arsenic precipitation and the purification under certain conditions.
Key words: magnetic field effect sulfidation precipitation of arsenic
