摘　　要：在盐酸介质中,利用四溴双酚A对类Fenton反应产生的羟基自由基氧化固绿的反应具有抑制作用原理,建立了一种用分光光度法测定塑料插座中四溴双酚A的分析方法,并考察了盐酸的用量、硫酸铁铵的用量、固绿FCF的用量、H2 O2溶液的用量、加热温度和反应时间等因素对体系的影响.在最佳实验条件下,方法的线性范围为2.0×10^（-5）～3.0×10^（-4） mg/mL,相关系数0.9934,检出限为5.6×10^（-7） mg/mL.该方法应用于塑料插座中的四溴双酚A的测定,测定结果的相对标准偏差（RSD）为3.2%～4.9%,回收率88%～108%.该方法操作简单,便于快速分析.In hydrochloric acid medium, Tetrabromobisphenol A can inhibit oxidative reaction of hydroxyl radical produced by Analogous Fenton reaction on discoloring Fast green FCF. Based on the reaction with inhibition principle, a new spectrophotometric method for the determination of level tetrabromobisphenol A in plastic socket is established. Effects of the amount of Hydrochloric acid, Ferric sulfate, Fast green FCF, H202, reaction tempera- ture, reaction time, and other factors are optimized. Under the optimum experimental conditions, a linear response of tetrabromobisphenol A is obtained over the range from 2.0 × 10^（-5） ～ 3.0 × 10^（-4）mg/mL, the correlation coeffi- cient is 0.9934, and with a limit of detect of 5.6 × 10^（-7） mg/mL. The proposed procedure is applied to determine the amount of tetrabromobisphenol A reached from plastic socket. The results of determination （RSD） is 3.2% ～ 4.9%, and the recovery range is 88% ～ 108%. The method has the advantages of simple operation, being conven- ient and quick analysis.
