Abstract
The invention discloses a method for treating dioctyl phthalate by using active carbon and Fenton reagent. The method comprises the following steps of: (1) dissolving the dioctyl phthalate by solvent, then, diluting the solution to the needed concentration by using distilled water; (2) regulating the pH of the prepared dioctyl phthalate solution, adding a certain amount of active carbon in the prepared dioctyl phthalate solution, stirring for a while at controlled stirring speed; 180min later, filtering to get the filtrate; (3) adding a certain amount of Fe<2+> and a certain amount of H2O2 of which mass fraction is 30% into the filtrate; (4) 150min later, taking the supernatant liquid for analysis and detection. The method obtains better treatment effect under the combined effect of active carbon and oxidant, the biochemical treatment process is not needed, the technological process is simplified, the investment and the operating cost can be effectively lowered, and engineering implementation applicability is very high.
