高效液相色谱法快速分析口香糖中戊二醛的残留量

Glutaraldehyde Residue Determination in Chutty by HPLC

建立了用高效液相色谱法检测口香糖中灭菌剂戊二醛残留量的方法。样品萃取液与2,4-二硝基苯肼反应后用高效液相色谱测定,外标法定量。该方法快速、准确,在0.2～5.0mg/L范围内线性相关系数为r2=0.9995,平均回收率达到77.2%～83.9%,相对标准偏差为4.95%～6.22%,最低检测浓度为0.2mg/L。

A method for the determination of glutaraldehyde residue in chutty by HPLC was developed. In the range of glutaraldehyde content of 0.2-5 mg/L, the method was fast and accurate with a linear correlation of 0.9995, average recoveries of 77.2 %～83.9 %, a relative standard deviation of 4.95 %～6.22 % and a minimum determination concentration ofO.2 mg/L.
