摘要
目的建立氧化型染发剂中邻苯二胺、对苯二胺、间苯二胺的气相色谱测定方法。方法样品经乙酸乙酯溶解,离心,萃取后的样液用毛细管柱气相色谱法进行定性和定量分析,并探讨了最佳条件。结果邻苯二胺、对苯二胺、间苯二胺的线性范围均为25～400μg/ml,其相关系数为0.9991～0.9999;方法最低检出限分别为3.1、3.6、3.4μg/ml;样品加标回收率为86.8%～104.3%,相对标准偏差为1.7%～4.6%(n=3)。结论该方法简单、快速,能有效萃取和分离氧化型染发剂中苯二胺化合物。
Objective To establish a method for determination of p-phenylenediamine,m-phenylenediamine,o-phenylenediamine in oxidative-type hair dyes.Methods The samples of oxidatve-type hair dyes were solved by ethyl acetate,then followed by centrifuged,extracted.The extraction was qualitatively and quantitatively analyzed by gas chromatography,the working condition was optimized also.Results The linear range for p-phenylenediamine,m-phenylenediamine,o-phenylenediamine was 25-400 μg/ml,r=0.999 1-0.999 9,the detection ...
