ActiveDetermination of arsenic, selenium and mercury in coal—Hydride generation-atomic fluorescence spectrometry
煤中砷、硒、汞的测定 氢化物发生-原子荧光光谱法
Application Summary AI generated
This standard specifies a method for determining trace amounts of arsenic, selenium, and mercury in coal using hydride generation-atomic fluorescence spectrometry. It is applied in coal quality analysis laboratories, mining operations, and environmental monitoring contexts to assess the concentration of these hazardous elements for pollution control and coal utilization safety. The method ensures accurate detection of these toxic elements, which is critical for evaluating coal's environmental impact and compliance with emission regulations.
