| 摘 要： | 研究了以４－氨基安替吡啉（４－ＡＰＰ）为显色剂，用一阶导数分光光度法直接测定炼油厂污水中微量苯胺的最佳条件。在ｐＨ５．５的ＨＣｌ－（ＣＨ２）６Ｎ４缓冲溶液中，４－ＡＡＰ与苯胺生成的配合物有较高的灵敏度，加入ＯＰ乳化剂显著地增加了其稳定性，用导数法的零交技术消除了苯酚等的干扰。本法的线性范围在０～４０μｍ／５０ｍｌ，检出限为０．０７μｍ／ｍｌ，加标回收率在９５％～１０９％之间。

Direct Determination of Aniline Content in Refinery Waste Water by4 Aminoantipyrine(4 AAP) Derivative Spectrophotometry |
| |
| Abstract: | method is proposed for the direct determination of aniline content in refinery waste water by 4 AAP derivative spectrophotometryInterferences such as phenol etccan be eliminated by the derivative zero crossing technique,so that no pretreatment procedure is necessaryA linear calibration curve was obtained in 0～40μg/50ml with a detection limit of 007μg/ml and a recovery of 95%～109%The proposed method has been applied successfully to the determination of aniline content in refinery waste water |
