GB/T 17136-1997 specifies cold Atomic absirption spectroscopy-tometry, AAS for the determination of total mercury content in soil. Absorbance is determined by cold atomic absorption spectrophotometer based on the absorption characteristics of mercury atoms to specific wavelengths of light by specific treatment of soil samples to convert mercury into detectable forms, so as to accurately calculate the total mercury content in soil. This standard provides a reliable total mercury detection method for soil mass monitoring, environment protection and other work, which is of great significance for understanding the status of soil mercury pollution and ensuring ecological environment security.
