摘要
目的：建立测定桃花散中朱砂、石膏的含量测定方法。方法：湿法消解样品，采用原子吸收分光光度法测定汞和钙含量后换算。结果：加样回收率为（９９８±２０）％和（９９６±２２）％。结论：本法操作简便，结果准确精密。可用于桃花散的定量标准。
OBJECTIVE: To determine cinnabar and gypsum in taohua san with atomic absorption spectrometer. METHODS: The sample was destroied by pressure tank and moist heat method. RESULTS: The average reclamation rates were (99820)% and (99622)% respectively. CONCLUSION: The method had high sensitivity,good reappearance.
