Diisobutyl phthalate degradation by Fenton treatment.
Degradation of diisobutyl phthalate (DIBP) by Fenton oxidation was evaluated in this study. The results indicate that the pH, H(2)O(2) and Fe(2 +) concentration were three main operating factors considerably affecting the decomposition of DIBP. The optimum conditions were observed at pH 3 and the molar ratio of [H(2)O(2)]: [Fe(2 +)]: [DIBP] = 5: 5: 1. Under such condition, the maximum removal of DIBP was as high as 87% at a time of 30 minutes. In general, the empirical equation was derived as follows: (dC(DIBP)/dt)(initial) = -k C(DIBP,0)(0.88)C(Fe2 +,0)(0.33)C(H2O2)(0.95).
