摘要

目的: 建立矿物药珍珠粉、玄明粉、炉甘石中主成分元素分析的电感耦合等离子原子发射光谱测定法。方法: 样品经微波消解后

采用电感耦合等离子体原子发射光谱法(ICP-OES) 分别测定珍珠粉、玄明粉、炉甘石中的钙、钠、锌元素。结果: 钙、锌、钠3种元素在0~20 mg·L-1线性关系良好(r为0.999 9~1.000 0)

重复性RSD分别为1.4%

1.5%

0.8%;加样回收率分别为105.0%

101.9%

104.5%

测定结果与火焰原子吸收光谱比较

结果一致。结论: 该法简便、灵敏、可靠

可较好的应用于矿物药及其复方制剂中的元素测定。

Abstract

Objective: To develop a method for determination of the main components elements in mineral drugs such as pearl powder

calamine and weathered sodium sulfate. Method: Calcium in pearl powder

zinc in calamine and sodium in weathered sodium sulfate were determined by ICP-OES after the samples were digested by microwave digestion system. Result: Calcium

zinc and sodium have a good liner in 0-20 mg·L-1 with the correlation coefficients 0.999 9-1.000 0

The RSD of repeatability for calcium

zinc and sodium were 1.4%

1.5% and 0.8%

and the recoveries were 105.0%

101.9% and 104.5%. The results matched the results of flame atomic absorption spectrometry. Conclusion: The method was simple

sensitive

and reliable.It can be applied in the determination of main components elements in pearl powder

calamine and weathered sodium sulfate and their componets.
