给出了 10 种明显不同的简要历史概述，尽管在某些情况下，经过检查，密切相关，流行的提出的反应机制及其相关的速率方程，其中每种机制的速率表达式源自附录 A 的基本原理。在附录 B 中，使用数据集测试了 5 种主要机制中的每一种，包括初始反应速率与有机污染物浓度 [P] 和入射辐照度，rho，数据，先前报告的 TiO2，其中 P 是苯酚、4-氯苯酚和甲酸酸。就整体拟合性、简单性、实用性和多功能性而言，测试中最好的是奥利斯提出的破坏吸附动力学模型。报告了构建这些机制时所做的通常基本假设，并探讨了主要的潜在问题。 (C) 2015 Elsevier B.V. 保留所有权利。
A brief, historical overview of 10 apparently different, although in some cases, upon inspection, closely related, popular proposed reaction mechanisms and their associated rate equations, is given and in which the rate expression for each mechanism is derived from basic principles, Appendix A. In Appendix B, each of the 5 main mechanisms are tested using datasets, comprising initial reaction rate vs. organic pollutant concentration, [P] and incident irradiance, rho, data, reported previously for TiO2, where P is phenol, 4-chlorophenol and formic acid. The best of those tested, in terms of overall fit, simplicity, usefulness and versatility is the disrupted adsorption kinetic model proposed by Ollis. The usual basic assumptions made in constructing these mechanisms are reported and the main underlying concerns explored. (C) 2015 Elsevier B.V. All rights reserved.
