中文摘要: 目的:建立测定酒石酸唑吡坦原料药中痕量钯的方法。方法:采用石墨炉原子吸收光谱法,样品用1%盐酸溶液溶解后直接测定。采用横向平台石墨管,检测波长为244.79 nm,光谱带宽为0.2 nm,空心阴极灯工作电流强度为6 mA,扣背景方式为塞曼效应,测量模式为峰高,进样量为20 μl。结果:钯的检测质量浓度线性范围为0~100 ng/ml(r=0.999 0);精密度、重复性试验的RSD≤2.0%;加样回收率为97.78%~103.07%,RSD=1.6%(n=9);检测限为1.48 ng/ml。结论:该方法操作简便、迅速,具有良好的精密度和准确度,可用于酒石酸唑吡坦原料药中痕量钯的测定。
英文摘要: OBJECTIVE:To establish a method for determination of trace platinum in zolpidem tartrate. METHODS: Graphite furnace atomic absorption spectrometry (GFAAS) was adopted for direct determination after dissolving sample in 1% Hydrochloric acid solution. Horizontal platform graphite tube was performed with detection wavelength of 244.79 nm, slit width of 0.2 nm and current intensity of hollow cathode lamp of 6 mA. The mode of background correction was zeeman effect, the peak height was used as measurement pattern, and the injection volume was 20 μl. RESULTS: The linear range of platinum was 0-100 ng/ml (r=0.999 0); RSDs of precision and reproducibility tests were no more than 2.0%; recovery was 97.78%-103.07% (RSD=1.6%,n=9); the detection limit was 1.48 ng/ml. CONCLUSIONS: This method is simple and rapid with good precision and accuracy, and can be applied for the determination of trace platinum in zolpidem tartrate.
