Abstract Wet oxidation processes such as Fenton and Fenton-like have been considered to treat radioactive ion exchange resins. This investigation demonstrates the oxidative dissolution of cation exchange resin beads by using a fluidized bed Fenton process. The cation exchange resin beads were firstly saturated with catalyst (Fe(II)) in the tubular reactor with a temperature control jacket, and then initiated the oxidation with injecting the H2O2 into the fluidized bed reactor. By means of adjusting a suitable amount of ferrous ions saturated on the cation IER, the reaction can be aimed on the IER destruction rather than homogeneous oxidation. The conversion of resins to gas and soluble fragments reached 91.6% under conditions of solid loading = 117.6 g/L, 25 mL H2O2 dosage (50 wt%), FeSO4 = 10 mM at 75 °C. The fluidized bed Fenton process is efficient and ready to control for the oxidation of cation exchange resin beads in heterogeneous catalysis.

使用流化床反应器通过 Fenton 法氧化溶解阳离子交换树脂

摘要 湿式氧化法如 Fenton 和 Fenton-like 已被考虑用于处理放射性离子交换树脂。该研究证明了使用流化床 Fenton 工艺对阳离子交换树脂珠粒进行氧化溶解。阳离子交换树脂珠首先在带有温度控制夹套的管式反应器中用催化剂（Fe（II））饱和，然后通过将 H2O2 注入流化床反应器中引发氧化。通过调节适量的亚铁离子饱和在阳离子IER上，反应可以针对IER的破坏而不是均相氧化。在固体负载 = 117.6 g/L、25 mL H2O2 用量（50 wt%）、FeSO4 = 10 mM 条件下，树脂向气体和可溶性碎片的转化率在 75 °C 下达到 91.6%。
