目的:建立小儿至宝丸中朱砂和雄黄的含量测定方法。方法:分别采用原子吸收分光光度法(AAS)和电感耦合等离子体发射光谱法(ICP-AES)测定小儿至宝丸朱砂中的汞和雄黄中的砷含量。结果:AAS法测定的汞的线性范围为5~100Rg·ml~(-1)(r=0.999 9),砷的线性范围为2~50μg·ml~(-1)(r=0.9992),汞的平均回收率为99.3%,RSD为3.0%(n=6),砷的平均回收率为104.5%,RSD为2.1%(n=6);ICP-AES法测定的汞的线性范围为0.1~20.0μg·ml~(-1)(r=0.99997),砷的线性范围为0.1-20.0μg·ml~(-1)(r=0.99999),汞的平均回收率为96.6%,RSD为1.4%(n=6),砷的平均回收率为104.1%,RSD为1.1%(n=6)。结论:本文建立的方法准确、专属性强,可用于控制小儿至宝丸中毒性成分的含量。
Objective: To establish a method for determination of cinnabar and realgar in children’s treasure. Methods: The contents of arsenic in Mercury and Realgar in Pediatric Cinnabar were determined by atomic absorption spectrophotometry (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) respectively. Results: The linear range of mercury was 5-100Rg · ml -1 (r = 0.999 9). The linear range of arsenic was 2 ~ 50μg · ml -1 (r = 0.9992). Mercury The average recovery was 99.3%, RSD was 3.0% (n = 6), average recovery of arsenic was 104.5% and RSD was 2.1% (n = 6). The linear range of mercury determination by ICP- The linear range of arsenic was 0.1-20.0 μg · ml -1 (r = 0.99999). The average mercury recovery was 96.6% and the RSD was 1.4% (n = 6). The average recovery of arsenic was 104.1% with a RSD of 1.1% (n = 6). Conclusion: The method established in this paper is accurate and specific, and can be used to control the content of toxic components in Children Po Chi Wan.
