| Abstract: | In this article, photocatalytic oxidation of I- in aqueous solution has been studied with a photocatalytic glass reactor.The using catalyst is made of the glass beads as the carrier, and on the surface of every bead an evenly transparent TiO2 thin film was covered by the sol-gel process.It has been observed that the yield of I2 formation is dependent on the crystal structure of the catalyst, the illumination time, the initial concentrations of I- and H+.The results show that the yield of I2 can reach 41.26% over anatase TiO2- coated film, with photocatalyst(4.0g) in the solution of KI(3L), I-] of 0.3mol· L-1, H+] of 3.0mol·L-1 and illumination time of 8h. |
