摘要

合成染料排放到环境中对人类健康和生态系统构成重大威胁,需要对污染水进行处理。采用高碘酸盐(PI)和氯(Cl2)在水溶液中产生自由基以消除直接蓝71 (DB71)染料。在本研究中,利用紫外线(UV)实现了PI和Cl2的分离活化。研究了各种操作参数的影响,结果表明染料在12分钟内完全降解。铁离子和铜离子的存在对两种体系的降解率都有轻微的增强作用。清除实验证实,在UV/PI系统中,HO•和IO3•是DB71降解的主要因子,而活性氯自由基在UV/Cl2过程中起主导作用。在矿化、实际废水应用和能源效率方面,UV/PI体系表现出略优于UV/Cl2体系的性能。

UV/periodate and UV/chlorine for dye degradation and real wastewater treatment: a comparative study
Abstract The discharge of synthetic dyes into the environment poses a significant threat to both human health and the ecosystem, necessitating the treatment of contaminated water. To generate free radicals for the elimination of Direct Blue 71 (DB71) dye from aqueous solutions, periodate (PI) and chlorine (Cl2) have been employed. In this study, separate activation of PI and Cl2 was achieved using ultraviolet (UV) light. The impact of various operational parameters was investigated, resulting in the complete degradation of the dye within 12 min. The presence of ferrous and copper ions had a minor enhancing effect on the degradation rate in both systems. Scavenging experiments confirmed that HO• and IO3• were the primary agents responsible for DB71 degradation in the UV/PI system, while reactive chlorine radicals played a dominant role in the UV/Cl2 process. In terms of mineralization, application for real wastewater and energy efficiency, the UV/PI system exhibited slightly superior performance compared to the UV/Cl2 system.
