英文摘要：

Catalytic degradation of naproxen in aqueous solution by ~~Co gamma-ray irradiation was studied. lhe influence of absorption dose, solution pH, the presence of additives （H202, CO~- and t-BuOH） on the degradation of naproxen were investigated. The results showed that gamma-ray irradiation was able to degrade naproxen in aqueous solutions successfully, and the radiolytic degradation of naproxen was in accordance with the pseudo-first-order kinetic model. When naproxen concentration of 23.6 mg＂ L-1 and an absorption dose of 1.0 kGy were chosen, naproxen degradation rate was 98%. The presence of 0.5% H~O2 enhanced the degradation process,however, 1.5% H202 additive inhibited the degradation of naproxen. Additives such as CO~- and t-BuOH also inhibited the degradation process.
