The introduction of Fe into supercritical water oxidation (SCWO) and the formation of Fenton reagent with oxidant HO form a new environment, namely, supercritical Fenton oxidation (SCFO) environment. -Aminonaphthalenesulfonic acid was selected as the typical organic pollutant to explore the effects of temperature, oxidant multiple, reaction time and Fenton conditions on the TOC removal rate. SCFO showed the superiority in the degradation of organic matter compared with the SCWO. The oxidative degradation kinetics of -aminonaphthalenesulfonic acid in SCFO environment was further explored. Under SCFO condition, the oxidative degradation of -aminonaphthalene sulfonic acid was consistent with first-order reaction kinetics. The results showed that the activation energy and pre exponential factor were 39.937 kJ·mol and 1.94 × 10 s respectively.
将铁引入超临界水氧化（SCWO）中，并与氧化剂 HO 形成芬顿试剂，形成了一种新的环境，即超临界芬顿氧化（SCFO）环境。-氨基萘磺酸被选为典型的有机污染物，以探讨温度、氧化剂倍数、反应时间和芬顿条件对总有机碳（TOC）去除率的影响。SCFO 在有机物降解方面表现出优于 SCWO 的性能。进一步探讨了 -氨基萘磺酸在 SCFO 环境中的氧化降解动力学。在 SCFO 条件下，-氨基萘磺酸的氧化降解符合一级反应动力学。结果表明，其活化能 和指前因子 分别为 39.937 kJ·mol 和 1.94 × 10 s。
