摘要
建立了气相色谱分析邻苯二甲酸酯的方法.选择邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸二正丁酯(DBP)、邻苯二甲酸丁苄酯(BBP)、邻苯二甲酸二(2-乙基己基)酯(DEHP)、邻苯二甲酸二正辛酯(DOP)7种标物,对实验方法的准确程度进行了分析.7种标物的线性相关系数都能达到0.999以上,线性范围在0.01～1g/L之间;保留时间的相对标准偏差都在0.1%以内,峰面积的相对标准偏差在2%以内.
A gas chromatography method was established to detect phthalates.With 7 kinds of phthalates including dimethylphthalate,diethylphthalate,di-iso-butylphthalate,dibutylphth-alate,benzylbutylphthalate,bis（2-ethylhexyl） phthalate,and dinoctylphthalate as the specimens,the accuracy of the detection method was examined.Results indicate that all the 7 kinds tested specimens can be determined at a linearity coefficient of above 0.999.Relevant linearity scope is between 0.01～1 g/L;relative standard deviation of retention time is below 0.1%,and relative standard deviation of peak area is below 2%.
