Arsenic Determination in Geological Samples by Atomic Fluorescence Spectrometry
Keywords:Atomic Fluorescence; Geological Samples; Arsenic.
An atomic fluorescence method was established for the determination of arsenic in geological samples . After sample digestion, arsenic reacts with potassium borohydride in a specific medium to produce volatile hydride. The fluorescence of characteristic wavelength is emitted under the irradiation of argon loaded quartz atomizer light source, and the fluorescence intensity is proportional to the content of elements.
