目的建立肾康注射液中铅、镉、砷、汞、铜的含量测定方法。方法肾康注射液采用微波消解法,采用原子吸收光谱法测定其中五种重金属的含量。结果肾康注射液中铅、镉、砷、汞、铜的加样回收率(n=9)分别为87.34%、89.98%、107.64%、105.98%、103.84%,RSD≤5%。结论建立的方法精密度高,重复性好,可用于该注射液中五种重金属及有害元素的质量监测。 Objective To establish a method for the determination of lead, cadmium, arsenic, mercury and copper in Shenkang injection. Methods Shenkang injection was determined by microwave digestion, and the contents of five heavy metals were determined by atomic absorption spectrometry. Results The recoveries (n = 9) of lead, cadmium, arsenic, mercury and copper in Shenkang injection were 87.34%, 89.98%, 107.64%, 105.98% and 103.84%, respectively. Conclusion The established method has high precision and good repeatability and can be used for quality monitoring of five heavy metals and harmful elements in the injection.
