| 摘 要： | 目的建立原子吸收分光光度法,测定骨碎补药材中的铅、镉、砷、汞、铜重金属含量。方法以原子吸收分光光度法在324.8 nm波长处检测铜含量,在283.3 nm波长处检测铅含量,在228.8 nm波长处检测镉含量;另采用原子荧光光谱法测定砷、汞的含量。结果 10批骨碎补药材中的重金属含量,铜为2.687 5～8.521 7 mg/kg,镉为0.200 6～0.270 8 mg/kg,铅为0.250 4～1.000 mg/kg,汞为0.003 4～0.029 4 mg/kg,砷0.006 6～0.053 3 mg/kg。结论 10批骨碎补样品中重金属含量均符合2005年版《中国药典(一部)》和香港《中成药注册申请手册》中有关重金属标准的规定。 |
