PFRs were produced on biochar during Cr(VI) decontamination. PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI). Appearance of excessive oxidant led to the consumption of PFRs on biochar. Biochar charred at high temperature possessed great performance to Cr(VI) removal.

Specific second-order rate constants were determined for 5-FU and CAP with ozone. Reaction sites were confirmed by kinetics, Fukui analysis, and products. The olefin moiety was the main ozone reaction site for 5-FU and CAP. Carboxylic acids comprised most of the residual TOC for 5-FU. Ozonation removed the toxicity associated with 5-FU and products but not CAP.

水力空化因其能效高、操作成本低、能够诱导化学反应并可规模化等优势,被认为是一种很有前途的工艺强化技术。近十年来,人们对水力空化及其主要变量的基本认识取得了一些进展,为水力空化在自由基诱导化学反应过程中的应用提供了基础。在这里,我们对这些研究工作进行了广泛回顾,包括水力空化的基本原理、空化反应器的设计、空化诱导的反应增强及相关的工业应用。比较了两种类型的水力空化反应器,即固定式和旋转式水力空化反应器。讨论了水力空化反应器的设计参数及其在实验室和中试尺度上的反应器性能,并就其最佳操作和几何条件提出了建议。本文首次回顾了目前市场上的商业空化反应器。水力空化的独特特点已广泛应用于各种化学反应,如氧化反应和废水处理,以及如乳化液生成和组分提取等物理过程。文中也详细讨论了自由基和气泡内爆的作用。
