摘　　要：通过优化分析仪器的条件设置，建立了使用气相色谱-电子捕获检测器技术分析四溴双酚-A（TBBP—A）的仪器分析方法。样品采用正己烷索氏提取、硅胶柱分离纯化、外标法定量，结果表明，测定方法在测量范围内具有良好的线性关系，测定的平均回收率为86．8％，检出限为5．0ng／ml，相对标准偏差为3．26％～8．77％：A gas cbromatography-electron capture detection（GC-ECD） method for determination of TBBP-A was developed by optimizing the operating conditions instrumentally. Samples were extracted with n-hexane in soxhlet tubes, and cleaned-up with silica gel column separation and then quantified with via external standard method. The results showed that this method had a good Xinear correlation with the measured range, the average recoveR, of measurement was 86.8% , the detection limit was 5.0 ng/ml, the relative standard deviation was 3.26% - 8.77%.
