摘要
系统研究了化学蒸气发生—原子荧光光谱法测定砷的条件,主要包括载气流速条件,屏蔽气流速条件,盐酸浓度和还原剂浓度等,在研究的实验条件下,测定了实际样品中药中的砷的含量,得到了满意效果。
In this paper,the determination of arsenic(As)was deeply studied by chemical vapor generation-atomic fluorescence spectrometry.The determination conditions were investigated,which were carrier gas flow rate,Shielding gas flow rate,Hydrochloric acid concentration,Potassium borohydride concentration,etc.In the optimal conditions,the actual samples(Traditional Chinese medicine)and standard samples were detected,and have a good result.
