摘要： 采用离子色谱法同时测定化妆品中氟离子、碘离子、溴酸根和氰根。对化妆品样品的前处理方法和仪器条件进行了优化,以氢氧化钠溶液进行梯度淋洗,阴离子分析柱(IonPacAS11-HC,250 mm×4 mm)分离,氰根采用电化学检测器进行定量,氟离子、碘离子和溴酸根采用电导检测器进行定量。结果表明,氟离子、溴酸根、碘离子和氰根的检出限分别为2.0,10.0,10.0和1.0 mg·kg-1。各离子的回收率为78.5%～110.6%,相对标准偏差为1.9%～6.9%。对实际样品进行检测,满足化妆品中多离子的检测要求。

Abstract: A method for simultaneous determination of ions of fluoride,iodide,bromate radical and cyanide radical in cosmetics by ion chromatography was established.Conditions for pre-treatment of samples of cosmetics as well as operation of the instrument were optimized.NaOH solution was used as gradient elution agent and the anions were separated by an analysis column (IonPacAS11-HC,250 mm×4 mm).Content of the cyanide radical ion was quantified by electrochemical detector,while the fluoride ion,iodide ion and bromate radical ion were quantified by conductivity detector.The detection limits of fluoride ion,bromate radical ion,iodide ion and cyanide radical ion are 2.0,10.0,10.0 and 1.0 mg·kg-1 respectively.The spiked recoveries are in the range of 78.5% to 110.6%.The relative standard deviations are 1.9% to 6.9%.The method can meet requirements of multiple ion detection in cosmetics.

Key words: cosmetics, ion chromatography, fluoride ion, iodide ion, bromate radical ion, cyanide radical ion
