| Abstract: | Using goethite as a catalyst,the degradation of PCB28 was studied in the heterogeneous Fenton system containing goethite and hydrogen peroxide (H2O2).The dosage effect of goethite and H2O2 and the pH of the system on the degradation efficiency of PCB28 were also discussed.Moreover,the degradation mechanism of PCB28 in the heterogeneous Fenton system was discovered.Results showed that PCB28 was significantly degraded in the heterogeneous Fenton system.The degradation efficiency of PCB28 increased with the in... |
