摘要
文章提供了一种冷原子吸收法测定药用丁基橡胶中汞含量的方法,以微波消解法制备样品,并对样品制备、还原剂浓度选择、标准曲线稳定性、加标回收率进行了研究。结果显示该方法适用于药用丁基橡胶中汞含量的测定,操作简便,成本低,能满足重金属含量管控的需求。
In this paper,a method for the determination of mercury content in medicinal butyl rubber by cold atomic absorption method was provided.Samples were prepared by micro wave digestion method,and the sample preparation,the selection of reducing agent concentration,stability of standard curve and recovery rate were studied.The results showed that this method was suitable for the determination of mercury content in medicinal butyl rubber,which was simple and low cost,and could meet the requirements of heavy metal content control.
