Scope
This standard is a new technology that combines hydride generation technology with atomic fluorescence spectrometry analysis technology to measure arsenic in water to achieve water sample detection. Compared with silver diethyldithiocarbamate spectrophotometry and potassium borohydride-silver nitrate spectrophotometry, atomic fluorescence photometry has the advantages of simple operation, less sample volume, high sensitivity and accuracy, and good measurement reproducibility. It has the characteristics of high degree of automation and suitable for large-scale analysis. This standard applies to the determination of arsenic in surface water, groundwater, atmospheric precipitation, sewage and their recycling water. The detection limit of the method is 0.2 μg/L, and the linearity is good in the range of 1 to 200 μg/L. Samples greater than 200 μg/L can be measured after dilution.
