AFS和ICP-OES测定固定污染源废气中砷的比较试验

Study on comparsion of Determination of Arsenic in Stationary Source Emission by AFS and ICP-OES

分别采用原子荧光分光光度法(AFS)和电感耦合等离子体发射光谱法(ICP-OES)对固定污染源废气中的砷进行了试验,比较了2种测试方法的优缺点。结果表明:2种方法都能满足测试要求,但AFS分析方法检出限低,灵敏度高,准确度高,测定范围广,ICP-OES适用于高含量样品的测定。

Atomic fluorescence spectrometry(AFS)and inductively coupled plasma optical emission spectrometry(ICP-OES)were used to test arsenic in exhaust gas from stationary source emission,and the advantages and disadvantages of the two test methods were compared.The results show that two methods all can meet the test requirements,but AFS has low detection limit,high sensitivity,high accuracy and wide range of determination.ICP-OES is suitable for the determination of high content samples.
