用氟离子选择性电极法对速效救心丸中氟进行了测定,其含量为:10.65×10~(-6)±0.13×10~(-6),回收率为98.2%～103.0%。说明用本法测定中药中氟含量精密度好,回收率离,方法简单。
Fluoride ion selective electrode method was used to determine the fluorine in Suxiao Jiuxin Pill. The content of fluoride was 10.65 × 10 -6 ± 0.13 × 10 -6, and the recovery was 98.2% -103.0%. This method is used to determine the fluorine content in traditional Chinese medicine precision, recovery rate, the method is simple.
