摘　　要：建立了高压聚乙烯装置过氧化物引发剂含量的气相色谱分析方法和高效液相色谱分析方法。测试结果表明,采用气相色谱法和液相色谱法的准确度和重复性较好,克服了碘量法测定时的误差,节省了分析的时间,避免应用有毒试剂,改善了分析环境。同时液相色谱法避免气相色谱分析时所述有机过氧化物高温易分解而无法准确测定的问题。A method for the determination of peroxide initiator in high pressure polyethylene plant by gas chromatography and high performance liquid chromatography was established. The test results show that the accuracy and repeatability of gas chromatography and liquid chromatography are good, overcome the error of iodometry, save the analysis time, avoid the application of toxic reagents and improve the analysis environment. At the same time, the liquid chromatography method avoids the problem that the organic peroxide is easy to decompose at high temperature and cannot be determined accurately during gas chromatography analysis.
