摘要
试验了萘乙二胺偶氮光度法测定苯胺的反应。结果表明 ,显色温度在 2 5℃ ,显色时间为 40min ,通过标样分析 ,相对误差为 - 0 2 %。对 4个废水水样进行测定结果表明 ,回收率在 97%～ 10 2 %之间。
The determination of anilines by spectrophotometry with N (1 Naphthyl) ethylenediamine was tested.The results showed that the developed temperature was at 25℃,the developed time was 40 minutes and the results were satisfactory.The relative error was -0.2% by analysis of standard sample and the recovery was 97%～102% by determination of four waste water samples.
