| titleOfInvention | By using C-MnO2Method for removing perfluorooctanoic acid in water by composite material |
| abstract | Use of C-MnO 2 A method for removing perfluorooctanoic acid in water by using a composite material relates to a method for removing perfluorooctanoic acid in water. The invention aims to solve the problems of low removal efficiency and high operation energy consumption of the existing technology for removing the perfluorooctanoic acid in water. The method comprises the following steps: firstly, ultrasonically oscillating activated carbon, graphite nanoparticles, carbon nanotubes or graphene nano sheets in water for 10-18 min, taking out, putting into a permanganate solution, reacting for 4-6 h under the stirring condition, wherein the reaction temperature is 65-75 ℃, and filtering and collecting to obtain C-MnO after the reaction is finished 2 A composite material; II, adding C-MnO 2 The composite material is put into water containing perfluorooctanoic acid, hydrogen peroxide is added, the reaction is carried out for 10min to 20min, and C-MnO is collected by filtration 2 And (4) compounding the materials to finish removing the perfluorooctanoic acid in the water. The invention can obtain a C-MnO 2 A method for efficiently removing perfluorooctanoic acid in water by using a composite material. |
