DETERMINATION OF ARSENIC IN WATER BY ATOMIC EMISSION-SPECTROMETRY USING HYDRIDE GENERATION TECHNIQUE

The use of various hydride generation techniques in atomic emission spectrometry for the determination of arsenic is reviewed. The valuation of these techniques is performed from the aspect of the simplicity and rate of analysis, and the detectability of the method. Continuous hydride generation is recommended for arsenic determination in water, and the connection of this technique with cryogenic trap collection mode, for the determination of extremely low arsenic concentration. Analytical efficiency of hydride generation in atomic absorbtion, and in atomic emission spectrometry is supposed to be identical.
