| 英文摘要 | Both transient photolysis and steady-state photo-degradation experiments were performed to gain insight into the kinetics and mechanisms of degradation of p-nitroaniline (p-NA) in acetonitrile (MeCN) solutions. Complete degradation of p-NA was observed at diverse irradiation conditions under 254 nm UV light. Once H(2)O(2) was added into the experimental system. degradation of p-NA was enhanced remarkably. The removal rate increased rapidly with increment of the irradiation time and reached 90% at 30 min. p-NA could be totally removed after 90 min in UV/H(2)O(2) process. In the presence of O(2) and H(2)O(2), removal rate increased linearly with increment of the irradiation time and reached 90% at 10 min. p-NA could be totally removed after 20 min in UV/(O(2) + H(2)O(2)) process. For transient photolysis, excited states of p-NA were observed after 355 and 266 nm laser flash photolysis (LFP). The transient absorption spectra were recorded and bimolecular rate constant of 6.89 x 109 M(-1) s(-1) was calculated for the self-quenching of (3)p-NA(*). Production of (3)p-NA(*) in MeCN and H(2)O mixed solution was also studied. LFP of p-NA with addition of H(2)O(2) was investigated for the first time. (c) 2008 Elsevier B.V. All rights reserved. |
