中文摘要：采用电感耦合等离子质谱仪对30批珍珠粉与珍珠层粉的微量元素进行测定,探讨珍珠粉与珍珠层粉中微量元素的特征差异。结果表明:海水珍珠粉和海水珍珠层粉中富集Na、Sr、K、Mg、B元素,而淡水珍珠粉和淡水珍珠粉层中富集Mn、Ba、Fe、Cr元素;淡水珍珠粉中Fe、K元素的含量高,淡水珍珠层粉中Mg、Cr元素的含量较高;海水珍珠粉和海水珍珠层粉之间无明显差异。

外文摘要：30 kinds of pearl powder and pearl layer powder were determinated by inductively coupled plasma mass spectrometer （ICP-MS） to investigate the different characteristics of trace elements in pearl powder and pearl layer powder.The results indicated that： （ 1 ） Seawater pearl powder and pearl layer powder had compara- tively abundant Na, St, K, Mg and B, whereas freshwater pearl powder and pearl layer powder contained rela- tively rich Mn, Ba, Fe and Cr. （2） Fe and K were of relative enrichment in pearl powder and Mg and Ca were of relative enrichment in pearl layer powder. （3） The content of trace elements was no significant between seawater pearl powder and its pearl layer powder.
