摘要: 建立了离子排斥色谱法对化妆品中硼酸及硼酸盐类进行检测。在对试样进行前处理后,采用ICS1100离子色谱仪对硼酸及其盐类进行测定,配置对硼酸根具有良好选择性的IonPac ICE-borate离子排斥色谱柱为分析柱,以甲磺酸-甘露醇为淋洗液,利用抑制电导检测器对化妆品中硼酸盐进行检测。结果表明,硼酸盐的检出限为0.57 mg/kg,定量下限为1.9 mg/kg,回收率在87%~108%之间,具有良好的回收率和重现性。

关键词: 化妆品, 硼酸盐, 离子排斥色谱

Abstract: The method of ion exclusion chromatography to detect boric acid and salt in cosmetics was established.After pretreatment of the samples,the boric acid and salt in samples was separated on ICS1100 ion chromatography system using IonPac ICE-borate ion exclusion column which has a good selectivity for borate radicals as analysis column,with methane sulfonic acid-mannitol as eluent,and suppressed conductivity detector to detect boric acid salts in cosmetics.Results showed that boric acid salt detection limit of this method is 0.57 mg/kg;the limit of quantification is 1.9 mg/kg;the recovery is in the range of 87%-108%,with good recovery and reproducibility.

Key words: cosmetics, borate, ion exclusion chromatography
