摘要
主要讨论了采用双波长分光光度法测定水样高锰酸盐指数 ,并通过与国家标准方法的测定结果进行比较 ,误差在 1 0 %以内 ,双波长分光光度法的精密度在 2 .81 %～ 4.0 5 % ,标准曲线方程为 y =1 3 46x0 .8864,且该方法应用范围广泛 .
The double wavelength spectrophotometric method of determining the index of permanganate in water is discussed.The results are compared with those of the national standard method,the relative error is less than 10%,and RSD is between 2.81% and 4.05%.The standard curve equation is y=1 346 x 0.886 4 . The method has extensive application range.
