摘要
本文采用自制电热恒温石英管还原气化冷原子吸收光谱法,直接测定了六味地黄丸中的痕量汞。方法检出限为0.1ppb;回收率为90—98％;相对标准偏差为4.3％。该方法简便,重现性好,准确度高,可用于中成药中痕量汞的测定。
Using a homemade device of the electric heated quartz-tube atomizer, including a controlling temperature unit and a continue hydride generator, trace mercury in,samples of traditional chinese medicine (Liu Wei Di Huang Wan) has been determined directly. The method is simple, convenient, and of good precision and high accuracy. It is a very practical method for the analysis of trace mercury. The detection limit is below 0. 1ppb, and the recovery is 90-98%.
