顶空-气相色谱-质谱联用法测定中小学教科书中25种挥发性有机化合物的研究OA
Determination of 25 Volatile Organic Compounds in Primary and Secondary School Textbooks by Headspace-Gas Chromatography-Mass Spectrometry
为扩大中小学教科书的挥发性有机化合物检测目标物范围,提出顶空-气相色谱-质谱联用法检测25种挥发性有机化合物(VOCs)的残留含量.实验结果表明,本方法分离效果良好,25种VOCs的回收率较好,相对标准偏差小于15％;本方法前处理简单,单样检测时间不到1 h.本方法比现有检测方法多检测出9种VOCs,为集中批量印刷的教科书提供了短期、更全面检测的可能,为中小学教科书的质量控制提供了有力支持.
In order to expand the scope of volatile organic compounds(VOCs)in primary and secondary school textbooks,headspace-gas chromatography-mass spectrometry was used to detect the residual content of 25 kinds of volatile organic compounds.The experimental results show that the method has good separation effect,the recovery rate of 25 VOCs is good,and the relative standard deviation is less than 15％.The pretreatment was simple and the detection time of sing…查看全部>>
