目的：建立原子吸收光谱法(AAS)测定药用炭中镉的含量。方法：样品灰化炽灼后，残渣加2ml盐酸，加热溶解，置50ml量瓶中，加水稀释至刻度，采用A A S法测定药用炭中镉的含量。结果：镉在0~0.4μ g/m L范围内线性关系良好，相关系数为0.9997；平均回收率为100.7%（n=6），RSD为0.9%。结论：本方法简单、快速、准确；可用于药用炭中镉的测定。
目的：建立原子吸收光譜法(AAS)測定藥用炭中鎘的含量。方法：樣品灰化熾灼後，殘渣加2ml鹽痠，加熱溶解，置50ml量瓶中，加水稀釋至刻度，採用A A S法測定藥用炭中鎘的含量。結果：鎘在0~0.4μ g/m L範圍內線性關繫良好，相關繫數為0.9997；平均迴收率為100.7%（n=6），RSD為0.9%。結論：本方法簡單、快速、準確；可用于藥用炭中鎘的測定。
목적：건립원자흡수광보법(AAS)측정약용탄중력적함량。방법：양품회화치작후，잔사가2ml염산，가열용해，치50ml량병중，가수희석지각도，채용A A S법측정약용탄중력적함량。결과：력재0~0.4μ g/m L범위내선성관계량호，상관계수위0.9997；평균회수솔위100.7%（n=6），RSD위0.9%。결론：본방법간단、쾌속、준학；가용우약용탄중력적측정。
Objective:To establish an AAS method to determine cadmium(Cd) in medical charcoal. Method: After ashing ignition, the sample was added hydrochloric acid 2ml to dissolve, the content of Cd in the samples was determined by AAS. Result:The good linear relation was obtained from 0 to 0.4μg/mL for Cd with a regression coefficient of 0.9997. The averaged recovery rate of potassium was 100.7%(n=6) with RSD of 0.9%. Conclusion:The method was simple, rapid and accurate, and can be used to control cadmium in medical charcoal.
