| 摘 要： | 在亚硝基铁氰化钾存在下，氨在氢氧化钠介质中与苯酚──次氯酸钠反应，其产物靛酚在滴汞电极上产生一灵敏的吸附波。用于环境水中NH_3-N的测定，其相对标准偏差小于3％，这种方法具有较好的选择性。

| Abstract: | It has been found that the reaction produce of NH3wiht phenol in agent of sodium hydroxide could produce a sensitive absorption wave at dropping mercury electrode in presence of K2FE(CN)5NO.This method has been used for determination of NH3 - N in environmental water with the relative standarddeviation less than 3%.this method may be of nice selectivity. |
