The GB/T 15505-1995 standard specifies a method for the determination of selenium in water and wastewater using graphite furnace Atomic absirption spectropho-tometry, AAS. It is suitable for the detection of water samples with selenium concentrations in the range of 0.015 to 0.2 mg/L, and the detection limit of the method is 0.003 mg/L. The standard describes in detail the detection principle, interference factors and their elimination methods, and the preparation and use of reagents to ensure accurate determination of selenium concentrations in complex water samples. This method is widely used in environment monitoring and water quality assessment.
