摘要
目的考察栽培柴胡药材的重金属含量情况。方法收集不同生长期施肥的柴胡,以原子吸收光谱法测定样品中的铅、镉、砷、汞和铜的含量。结果所有样品的铅、镉、砷、汞、铜的含量均未超出限量范围。结论该法快速、可靠,为柴胡重金属元素的测定提供了一种简便方法。
Objective To investigate the contents of heavy metals in Radix Bupleuri.MethodsAtomic absorption spectroscopy was used to determine the contents of Pb,Cd,As,Hg,Cu in Radix Bupleuri with different fertilizers.ResultsThe contents of Pb,Cd,As,Hg and Cu in all of 23 samples were within the limitation.ConclusionThis method is rapid and reliable.It is a simple method for the determination of heavy elements in Radix Bupleuri.
