Abstract:
Objective:To determine the content of lead, cadmium, arsenic, mercury and copper in Xiaohuoluo pills produced by 34 enterprises. Methods:Using microwave digestion, the contents of lead, cadmium and arsenic were determined by graphite furnace atomic absorption spectrometry;the content of mercury was determined by hydride generation atomic absorption spectrophotometry;the content of copper was determined by air-acetylene flame atomic absorption. Results: Lead, cadmium, arsenic and mercury in Xiao-huoluo pills from 34 different manufacturers were beyond the limits in various degrees. Conclusion: The method is simple and accu-rate, and can be used in the heavy metal determination of Xiaohuoluo pills.
