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.
