摘要：

Three kinds of new spectrophotometric methods for determining trace aniline in water were proposed. Aniline is coupled with guaiacol 8-hydroxy-quinoline or 1-naphthol in alkaline medium (pH = 12.2). The formed azo compounds have maximum absorption at 452,482 and 497 nm respectively against reagent blanks, Compared with N-(1-naphthyl)-ethylenediamine spectrophotometric method, these new methods are more convenient, rapid and sensitive. The limits of detection are 8.6, 10 and 14 mug/L, Beer's law is valid in the range of 0 similar to 5.6, 0 similar to 4.8 and 0 similar to 3.2 mg/L respectively. These new methods have been successfully applied to the determination of aniline in environmental water.
