摘要
目的建立珍珠粉中的多种重金属元素的一次分析的试验方法。方法采用电感耦合等离子体发射光谱法(ICP-OES法),测定珍珠粉中Cu、Hg、Pb、Zn、Fe、Cr、Ni、Cd、Ba、As、Mn金属元素的含量。结果在检测的样品中发现Mn、Fe、Ba的含量较高,分别为571.99,170.67,37.08μg·g-1(n=3)。结论 ICP-OES可以快速准备测定珍珠粉的多种金属元素;试验结果可为珍珠粉的质量标准制定提供参考。
OBJECTIVE To establish a method to determin the heavy metal elements in pearl powder. METHODS The heavy metal elements of pearl powder such as Cu,Hg,Pb,Zn,Fe,Cr,Ni,Cd,Ba,As,Mn were determined by ICP-OES. RESULTS The contents of Mn,Fe,Ba were higher in the tested samples,their contents were 571. 99,170. 67,37. 08 μg · g-1( n = 3),respectively.CONCLUSION The established method can be used for the rapid determination of various metal elements in pearl powder,and provide a reference for the quality standard of pearl powder.
