摘　　要：为了建立液相色谱测定盘式蚊香燃烧灰烬中醛酮类化合物含量的方法,文章采用水对盘式蚊香燃烧灰烬中的醛酮化合物进行提取,与2,4-二硝基苯肼(DNPH)溶液发生衍生化反应,用溶剂萃取衍生物后,再用液相色谱仪对其测定。结果显示,建立的液相色谱测定盘式蚊香燃烧灰烬中醛酮化合物含量的方法,在一定范围内线性良好,相关系数均在0.9991~0.9995,检出限0.28~1.36 mg/L,用于盘式蚊香样品测定时相关物质的相对标准偏差9.92%~14.97%。因此,文章建立的液相色谱测定方法可用于盘式蚊香燃烧灰烬中醛酮类化合物的测定。To establish a method for the determination of aldehydes and ketones in combustion ashes of mosquito repellent incense by HPLC,aldehydes and ketones were extracted from the burning ashes of mosquito repellent incense with water in this paper.The derivatives were extracted by solvent and then determined by HPLC.The results showed that the method of HPLC was established to determine the content of aldehydes in the combustion ashes of mosquito repellent incense.The linear range was good,the correlation coefficient was 0.9991-0.9995,the detection limit was0.28-1.36 mg/L,and the relative standard deviation of the related substances was 9.92%-14.97%when used in the determination of the mosquito repellent incense samples.The method can be used to determine aldehydes and ketones in the ash of mosquito incense burning.
