摘要
利用稳态分析技术对4-氯酚稀水溶液在多种条件下的γ辐解产物进行了详细研究。用pH计、氯离子选择电极、TOC分析仪等对4-氯酚水溶液的不同辐解体系在降解过程中与氧化性自由基羟基和还原性粒子水合电子作用后的pH值、Cl-浓度、TOC的变化进行了跟踪;并通过HPLC对辐照后的产物进行分析,为4-氯酚的辐射降解工艺研究提供了理论基础。
The 4-chlorophenol degradation in dilute aqueous solutions under different conditions was studied by γ radiolysis steady analysis technology. The pH value, chloride concentration, TOC value were followed in the degradation process of 4-chlorphenol in OH-induced oxidative systems and eeq-induced reductive system by combining y radiolysis with various analytical techniques, and the products were qualitatively analysed by HPLC, this can give some advice to study 4-chlorophenol radiolysis degradation.
