| description | The invention relates to the technical field of wastewater adsorption methods, in particular to a method for adsorbing perfluorooctanoic acid in wastewater. The method comprises the following steps: S1, adding a reagent into the wastewater containing perfluorooctanoic acid to adjust the pH value of the wastewater; s2, after the pH value is adjusted, adding copper sulfide solid particles into the wastewater containing the perfluorooctanoic acid, and then stirring under a constant-temperature condition to enable the copper sulfide solid particles to adsorb the perfluorooctanoic acid in the wastewater; wherein the optimal molar ratio of the copper sulfide solid particles to the perfluorooctanoic acid is 1: 10. According to the method, the adsorption effect of the copper sulfide on the perfluorooctanoic acid is good, other agents do not need to be added in the reaction process, and the adsorption capacity of the copper sulfide on the PFOA can reach 451.76 mg/g under the conditions that the temperature is 30 DEG C |
