- Efficiently-solubilizing anionic Gemini surfactant used for chlorinated hydrocarbon pollutants and synthesis method of efficiently-solubilizing anionic Gemini surfactant used for chlorinated hydrocarbon pollutants
-
The invention relates to an efficiently-solubilizing anionic Gemini surfactant used for chlorinated hydrocarbon pollutants and a synthesis method of the efficiently-solubilizing anionic Gemini surfactant used for the chlorinated hydrocarbon pollutants. After being dissolved in water, the synthesized ethylene glycol di-maleic acid 1-decanol diester sulfonate Gemini surfactant (GS-10) forms electronegative micelle under a condition of a concentration higher than a critical micelle concentration, and hydrophobic chlorinated hydrocarbons, such as TCE and PCE, enter the micelle to increase the apparent solubility of the pollutants in the water. The efficiently-solubilizing anionic Gemini surfactant used for the chlorinated hydrocarbon pollutants can be preferably used for an underground water surfactant in-situ flushing technology to remove residual chlorinated hydrocarbon pollutants in aquifers, and has wide application.
