Abstract

In this paper, the hydrated electron (e_aq^-) was formed by the electron beam irradiation of water and the result showed that the reductive e_aq^- could not degrade 4-tert-butylphenol (4-t-BP). The hydroxyl radical (·OH) was formed by the UV_254nm irradiation of H₂O₂ and the degradation of 4-t-BP was very efficient. The experimental parameters such as initial concentration of 4-t-BP, H₂O₂ adding concentration and pH value of the solution were discussed. The results showed that low concentration of 4-t-BP and high concentration of H₂O₂ were favorable to the reaction. The optimum pH was 6. The intermediate products were analyzed by HPLC and GC-MS. 4-tert-butylcatechol, 4-tert-butylphenol dimer and hydroquinone were detected. The 4-t-BP degradation pathway was summarized according to these intermediate products.

Key words： hydroxyl radical hydrated electron 254nm UV photodegradation 4-t-BP
