摘要
经实验证明,用H_2O_2氧化次甲基绿——催化分光光度法测定痕量Fe^(3+),测定仪器比较简单,具有较高的选择性。同时减少了原子吸收法测量的繁琐的预处理,本文确定了最佳实验条件,并对标准样品和实验样品进行了分析,结果理想。
We determine trace Fe3+ with H2O2 oxidize hypo- methylene-catalytic spec-
trophotomery. This method needs simpler instruments, has higher selectivity and can reduce complicate pre - treatment of atom absorption method. In this paper, we define optimum experiment condition .analyse standard samples and experiment samples and have satisfactory result.
