Determination of Selenium in Water by Atomic Fluorescence Spectrometry with Ferric Chloride as Masking Agent
In this paper,it is found that when the concentration of Cu2+in water is less than 500μg/L,it will in-terfere with the result of selenium determination by atomic fluorescence method.When the measurement is greater than 500μg/L,the result will be seriously low.Therefore,potassium ferricyanide or ferric chloride solution can be added for masking.At the same time,because potassium ferricyanide solution may decompose when it is exposed to light or heat,resulting in toxic substances,it is recommended to use ferric chloride as a masking agent.
