目的:建立石墨炉原子吸收法检测注射用顺铂中铂(Pt)的含量。方法:检测波长:265.9 nm,灯电流:12.0 mA,狭缝宽度:0.4 nm,载气流量:200 ml·min~(-1)。结果:Pt在100～500μg·L~(-1)范围内线性关系良好(r=0.999 9),平均加样回收率为99.03%(RSD=0.3%,n=9)。结论:该方法可有效控制注射用顺铂的质量,方法简单、结果准确、灵敏度高 Objective: To establish a graphite furnace atomic absorption spectrometry for the determination of platinum (Pt) in cisplatin for injection. Methods: The detection wavelength was 265.9 nm, the lamp current was 12.0 mA, the slit width was 0.4 nm and the carrier gas flow rate was 200 ml · min ~ (-1). Results: The linearity of Pt in the range of 100-500 μg · L -1 was good (r = 0.999 9). The average recovery was 99.03% (RSD = 0.3%, n = 9). Conclusion: This method can effectively control the quality of cisplatin for injection, with simple method, accurate result and high sensitivity
