摘要
应用微波消解仪和原子吸收光谱仪 ,采用氢化物 冷原子吸收光谱法对人参中的汞的定量测定方法进行了研究和探讨。对微波消解仪的消解条件、氢化物 冷原子吸收法的测定条件进行了探讨。在本文选择的条件下 ,回收率为 90 98%~ 1 0 8 96% ,相对标准偏差为 8 0 4 %~ 1 5 77%。
The method of determination of Hg in ginseng by cold atomic absorption spectrometry was presented.The determination conditions were studied.Under the certain conditions,the recovery was 90 98%~108 96%.The relative deviation was 8 04%~15 77%.There was no obvious difference from the national standards.
