摘要

目的:建立火焰原子吸收光谱法测定药用辅料硬脂酸镁中痕量铅、镍、镉的含量。方法:药用辅料硬脂酸镁经微波消解或经湿法消解后

采用火焰-原子吸收光谱法测定痕量铅、镍、镉

并同时考察这两种样品处理方法对测定结果的影响。结果:微波消解法对样品测定结果优于湿法消解;镉0.42～1.12 mg·L-1

镍3.80～4.06 mg·L-1

铅5.07～10.31 mg·L-1。在选定分析条件下

镉、镍、铅检出限分别为0.001 2

0.002 9

0.003 4 mg·L

RSD分别为0.2%

2.9%

2.7%

回收率分别为为109.18%

101.30%

99.69%。结论:本法具有操作简单、灵敏度高、重复性好等优点

能满足痕量铅、镍、镉的测定要求

为药用辅料硬脂酸镁的质量控制提供依据。

Abstract

Objective:Set up a flame-atomic absorption spectroscopy method with cadmium

niccolum

and lead in oficinal magnesium stearate.Method:Oficinal magnesium stearate disposed via microwave digestion or ac-customed digestion

adopting Flame-Atomic Absorption Spectroscopy to determine trace amount lead

niccolum

and cadmium

and review the influence of determination from both disposal.Result:The result of determination by micro-wave digestion is better than accustomed digestion.The results of determination are as follows:cadmium was 0.42-1.12 mg·L-1

niccolum was 3.80-4.06 mg·L-1

lead was 5.07-10.31 mg·L-1.The limit of determination of cad-mium

niccolum

and lead are 0.001 2

0.002 9

0.003 4 mg·L-1

the RSD are 0.2%

2.9%

2.7%

the recovery are 109.18%

101.30%

99.69%.Conclusion:This method possesses excellence of simplify manipulation

high ve-racity and nicer repeatability.It can content the need of trace amount

cadmium

niccolum

and lead determination and offer basis for quality control of oficinal magnesium stearate.
