This standard specifies a high-performance liquid chromatography method for the determination of glyphosate in soils and sediments. This standard is published for the first time. This standard is organized and formulated by the Ecological Environment Monitoring Department and the Regulations and Standards Department of the Ministry of Ecology and Environment. This standard was drafted by: Nanjing Institute of Environmental Science, Ministry of Ecology and Environment. Verification units for this standard: Jiangsu Provincial Environmental Monitoring Center, Jiangsu Provincial Nanjing Environmental Monitoring Center, Jiangsu Provincial Changzhou Environmental Monitoring Center, Jiangsu Provincial Zhenjiang Environmental Monitoring Center, Hulunbuir City Environmental Monitoring Center Station, Guangxi Zhuang Autonomous Region Nanning Ecological Environment Monitoring Center. This standard was approved by the Ministry of Ecology and Environment on October 24, 2019. This standard will be implemented from April 24, 2020. This standard is interpreted by the Ministry of Ecology and Environment. HJ1055-2019 "Determination of glycyrrhizinate" in soil and sediments by high performance liquid chromatography Warning: The solvents and standard solutions used in the experiment are toxic and harmful substances. Solution preparation and sample preparation should be carried out in a fume hood. Wear protective equipment as required during operation and avoid contact with skin and clothing. This standard specifies a high-performance liquid chromatography method for the determination of glyphosate in soils and sediments. This standard applies to the determination of glycerin in soil and sediments. When the sampling amount is 10g (and dry weight), the detection limit of this method is 0.02 mg/kg, and the lower limit of determination is 0.08 mg/kg.
