This standard specifies a method for the determination of selenium content in water by using 2,3-diaminonaphthalene fluorescence method. It is suitable for the determination of selenium in various clean water, domestic sewage and certain industrial wastewater, including organic selenium, inorganic selenium and their different valence states. This method can effectively detect trace selenium content through Fluorscence analysis, with a minimum detection concentration of 0.25 μg/L, and can eliminate the interference of heavy metals ions such as copper and iron by using EDTA and other reagents. It is suitable for wide application in water quality monitoring and environment testing.
