    Abstract:

    As is required to be immobilized as a stable compound, since it is produced as byproducts in nonferrous metal processes, typically copper smelting. A novel method for synthesizing large size scorodite particles was developed for removal of high concentration of arsenic in aqueous solution. This method involves the coprecipitation of scorodite particles from an Fe(II) and As(V) aqueous solution at a high temperature by oxygen injection. In order to investigate the stability of scorodite particles, dissolution tests of As in different aqueous solutions were carried out in this study. The results showed that the dissolved amounts of As from the large scorodite particles prepared by this process are very low, although they depend on pH of aqueous solution. The dissolution process of scorodite particles synthesized by the present method is discussed coupled with synthesis conditions of the scorodite particles.
