Industrial wastewater detection-Dimethylformamide in wastewaterDMF detection

summary:

Dimethylformamide (DMF) is a transparent liquid that is miscible with water and most organic solvents. It is a commonly used solvent in chemical reactions. It is a good solvent for various polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc., and can be used for wet spinning of polyacrylonitrile fibers and synthesis of polyurethane; Used for plastic film production; It can also be used as a paint remover to remove paint; It can also dissolve certain low solubility pigments, giving them the characteristics of dyes. Widely used in the leather, pharmaceutical, petrochemical, and organic synthesis industries, it is often referred to as a "universal solvent". Due to the large amount of DMF used in industry, untreated industrial wastewater usually contains high levels of DMF. In order to maintain the ecological environment, meet the requirements of sustainable industrial and environmental development, and timely, accurately, and effectively detect the content of DMF in industrial wastewater, Shanghai Xuansheng Company uses stainless steel chromatography columns, combined with FID detectors, and adopts the area external standard method to detect the content of DMF in industrial wastewater. The detection limit of this method is 5ug/ml.
