摘要
在pH=5.6的醋酸-醋酸钠缓冲介质中,痕量铝(Ⅲ)能灵敏地催化KIO4氧化萘酚绿B褪色,本文研究了该催化褪色反应的最佳动力学条件和参数,建立了测定痕量铝(Ⅲ)的催化动力学新方法,将其用于自来水、湖水中铝的测定,结果满意。
The decolorizing reaction of hydrogen peroxide and pyrogallol red byCobalt as a catalyst in boric acid and sodium carbonate medium was stu-died. The linear range is from 1×10^(-11) to 2.4×10^(-10)g/ml and the limit of detect-ionis 2.1×^(-12)g/ml. The coeffieient of variance is from 3.15% to 9.10%
