Growth and characterization of scorodite crystals from an aqueous solution by photo catalysis method

Abstract

  Scorodite crystals have been paid much attention to immobilize (insolubilize) arsenic. In this paper, new synthesis method of scorodite crystals has been investigated and scorodite crystals have been successfully grown for the first time by photocatalysis method using UV light irradiation. Formation behavior of scorodite crystals with UV light irradiation was also examined and compared with the method of O₂ gas injection.
