摘要
采用高效液相色谱-电感耦合等离子体-质谱联用技术（HPLC—ICP—Ms）测定皮革中Cr（Ⅵ）含量。该法简便、快速、灵敏度高，不受样液颜色干扰，在色谱进样量为100μL，质谱采用He碰撞池模式下，对Cr（Ⅵ）的检出限达到O．02μg/L；两个加标水平2．00、20．00μg/L下的回收率分别为93．5％-97．0％和97．8％-102．3％，方法精密度优于4．1％，可以满足测定要求。应用该方法测定各类皮革产品中的Cr（Ⅵ），分析结果令人满意。
A method for the determination of chromium（Ⅵ） in leather by high performance liquid chromatography-inductively coupled plasma mass spectrometry （HPLC-ICP-MS） is developed. This method is simple, convenient, quick and sensitive, and the result won＇t be disturbed by the shades of sample solutions. The detection limit is 0.02 μg/L of Cr（Ⅵ） for 100 μL injection sample in He collision cell mode of mass spectrometry. The recoveries are 93.5 % - 97.0 % and 97.8 %-102.3 % for the spiked levels of 2.00 μg/L and 20.0 μg/L respectively. The precision is less than 4.1%, and can meet the requirements of determination. This method has been used to determine Cr（Ⅵ） in several kinds of leather products and satisfactory results are obtained.
