| Abstract: | A photocatalytical degradation of 1-naphthol in aqueous solution by using the two-step microwave radiation under the UV light condition was investigated, with TiO2 as catalyst and H2O2 as oxidant. Results show that the removing rate of CODcr and TOC are 86.49% and 89.36% respectively. By analyzing the timing multi-point GC/MS data of the intermediate products in the whole degradation process, more than sixty kinds of intermediated products were caught. Through the method of analyzing induction, three main pathways which can reflect the panorama of the 1-naphthol degradation reaction paths were put forward. It is a beneficial exploration into the degradation of 1-naphthol aqueous on both theoretical and practical levels of study. |
