摘　　要：目的建立电感耦合等离子体质谱（ICP—MS）法测定海参胶囊中A1（铝）的残留量方法。方法采用微波消解，以钪为内标，ICP—MS法测定铝元素的残留量。结果Al（铝）的标准曲线的相关系数0．9977，回收率为95．6％-100．4％（n=3），其RSD在0．9％～2．4％。结论本法灵敏度高，简便，易行，结果准确可靠，可用于海参胶囊中铝的测定，可为海参胶囊中的质量控制提供依据。Objective To establish the inductively coupled plasma mass spectrometry （ ICP - MS） method for determination of aluminum in sea cucumber capsule. Methods The sample was treated with microwave digestion system, then based on Sc as internal standard, ICP - MS method was used for determination of aluminum residues. Results The correlation coefficient of A1 （aluminum） standard curve was 0. 9977, the recovery rate was 95.6% - 100.4% （ n = 3 ）, the RSD was between 0.9% - 2.4%. Conclusion The method is simple, fast, accurate, high sensitive, easy to operate, and it can be used for determina- tion of aluminum in the sea cucumber capsule.
