| titleOfInvention | Removal of anionic surfactants in wastewater |
| abstract | (57) [Summary] [PROBLEMS] A novel treatment method for removing anionic surfactants in wastewater in a small-scale facility. SOLUTION: The present invention relates to a method for easily performing a synthetic anionic surfactant in wastewater in a relatively small-scale facility. The first method is to put an aqueous solution containing an anionic surfactant and sodium chloride in the cathode compartment, put an aqueous solution of sodium chloride in the anode compartment, place a cellophane membrane or other diaphragm between the two compartments, place the iron mesh on the anode, In this method, a direct current is passed using carbon as a cathode. As a result, the anionic surfactant in the cathode chamber moves into the anode chamber, and combines with the iron ions generated there to be removed by precipitation. A second method is to remove the anionic surfactant by binding the cationic dye and the anionic surfactant in an aqueous solution, and passing this through an adsorptive solid represented by silica gel, Alternatively, a method in which a cationic dye is preliminarily supported on an adsorptive solid and then removed through an aqueous solution containing an anionic surfactant. By using these methods, an anionic surfactant in wastewater can be easily treated in a relatively small facility. |
