为研究水溶液中五氯酚的γ辐照降解效果,该文测定了辐照前后的五氯酚、氯离子浓度以及生物毒性的变化情况,考察了五氯酚初始浓度对其辐解效果的影响。结果表明:γ辐照可有效降解水溶液中的五氯酚,降解过程符合准一级动力学方程,五氯酚初始浓度为25、50mg.L-1,辐照剂量在4、6kGy时,其去除率可达100%。辐照可明显降低五氯酚溶液的生物毒性。
In order to study the degradation effect of pentachlorophenol in aqueous solution, the changes of pentachlorophenol, chloride ion concentration and biological toxicity before and after irradiation were measured. The effect of initial concentration of pentachlorophenol on its radiolysis effect was investigated . The results showed that γ irradiation could effectively degrade pentachlorophenol in aqueous solution. The degradation process was in accordance with pseudo first-order kinetic equation. The initial concentration of pentachlorophenol was 25 and 50 mg.L-1. When the irradiation dose was 4 and 6 kGy, Removal rate up to 100%. Radiation can significantly reduce the biological toxicity of pentachlorophenol solution.
