摘要
用硝酸和过氧化氢消化样品,通过基体改进剂,使用火焰原子吸收光谱法测定苦黄注射液及其中药材大黄、茵陈、柴胡、苦参中铜、铁、锌、钾和钠的含量。方法的回收率在92.6%~112.1%之间,相对标准偏差小于4%。
FAAS was applied to the determination of Cu, Fe, Zn, K and Na in Kuhuang injection and the raw Chinese medicines, Chinese rhubarb, capillary arternisia, root of chinse thorowax, kushen and etc, using HCl (2+ 98) and n-butyl alcohol (6+94) as matrix modifier for iron and zinc respectively, and HNO3 (2+98) as matrix modifier for copper, potassium and sodium. The results of analysis of 5 above-mentioned medicine samples gave RSD's less than 4% and recoveries in the range of 92. 6%-112. 1%.
