• 中文摘要： 以陽極氧化法在不同條件下製備光觸媒二氧化鈦電極,並以伏安法探討此電極破除水溶液中氰化物之行為。文中並討論攙雜離子(包括鋁離子、鎳離子、銅離子)及熱處理對二氧化鈦電極之光電化學影響。結果顯示在不同電解液中以硫酸浴所得電極破除氰化物之光電流影響應最大。攙雜離子對氰化物破除效率之影響不明顯,熱處理能促進破除氰化物光觸媒二氧化鈦電極之特性。
• 英文摘要： The voltammetric responses for destruction of cyanide in aqueous solutions with the photocatalytic TiO/sub 2/ electrodes prepared by the anodization of titanium under different conditions were investigated. The effects of doping species involving aluminum, nickel, and copper ions and heat treatment on the photo-electrochemical responses of TiO/sub 2/ electrodes were also studied. The results indicated that the photocurrent for destruction of cyanide with TiO/sub 2/ electrode prepared by the anodization of titanium in sulfuric acid solution was the best among those electrodes. The effects of doping ions on the destruction effiency of cyanide were insignificant. The performance of photocatalytic TiO/sub 2/ electrode for destruction of cyanide could be improved by heat treatment.
