中文摘要: 硫酸根自由基具有比羟基自由基更高的氧化还原电位,相对于传统的Fenton技术,基于硫酸根自由基的高级氧化技术其氧化能力更强,对有机物矿化程度更高。本项目采用过硫酸氢钾为氧化剂,结合自制铜基非均相催化剂处理有机废水,初步实验表明铜基非均相催化剂/过硫酸氢钾催化氧化体系处理有机物具有反应速度快、pH范围宽泛、催化剂可重复利用等优点。本项目拟进一步设计实验方案并采用一系列分析测试手段,研究常温常压下铜基非均相催化剂/过硫酸氢钾催化氧化体系的构建及反应机制。通过制备不同形态的铜基催化剂,研究催化剂结构和催化性能的相关性,确定催化剂制备过程中的调控参数。研究反应中各因素的影响,优化该催化氧化体系的反应条件。在此基础上,研制出在硫酸根自由基高级氧化体系中具有高催化活性的催化剂,并探讨该体系的反应机理。铜基非均相催化剂/过硫酸氢钾催化氧化可作为一种易于实现的高级氧化技术,为处理有机废水提供高效解决途径。

英文摘要: Because the sulphate radical has higher redox potential than hydroxyl radical, so compared to the traditional Fenton technology, the advanced oxidation technology based on the sulphate radical has unique advantages, such as stronger oxidation ability, higher mineralization degree of organic compounds. The project used potassium peroxymonosulfate as an oxidant, combined with self-made copper-based heterogeneous catalyst for the treatment of organic wastewater. Preliminary experiments have shown that copper-based heterogeneous catalyst /potassium peroxymonosulfate catalytic oxidation system has rapid reaction speed, less catalyst dosage, wide pH range, and reusable catalyst for the organic matter oxidation process. The further research will design some experimental program and adopted a series of analytical testing methods to study the construction and reaction mechanism of copper-based heterogeneous catalyst/potassium peroxymonosulfate catalytic oxidation system under ambient conditions. By the preparation of different forms of copper-based catalyst, the correlation between the catalyst structure and catalytic properties will be studied and the control parameters in the catalyst preparation process will be determined. By studying various factors of the reaction we will determine the optimal reaction conditions fo
