摘要/Abstract

摘要： 本文以对氯苯酚(4-CP)、对硝基苯酚(4-NP)和罗丹明B(Rh B)为模型有机物(以4-CP和4-NP为小分子模型有机物,以Rh B为大分子模型有机物),分别研究了185 nm UV对水中这3种模型有机物的降解规律、性能和效果.研究结果表明,185 nm UV直接对水中4-CP、4-NP和Rh B有很好的降解效果.研究内容包括:185 nm UV降解模型有机物的浓度、TOC(Total organic carbon)浓度、185 nm UV降解模型有机物过程中溶液pH及电导率变化、以及降解模型有机物过程中产生的无机离子等几个方面.

关键词: 废水, 对氯苯酚, 对硝基苯酚, 罗丹明B, 降解, 总有机碳, 185nmUV

Abstract: 4-Chlorophenol(4-CP),4-Nitrophenol(4-NP) and Rhodamine B(Rh B) are taken as model organic compounds(with 4-CP and 4-NP as small molecule model organic compounds and with Rh B as large molecule model organic compound) in the paper.Rule of degradation,performance and effect of these three kinds of model organic compounds in water by 185 nm UV irradiation are researched respectively.There is a very good degradation effect on 4-CP,4-NP and Rh B in water directly by 185 nm UV irradiation.The research respectively.There is a very good degradat ion effect on 4-CP,4-NP and Rh B in water directly by 185 nm UV irradiation.The research content includes:concentration of model organic substance by 185 nm UV irradiation,TOC concent ration,change of pH value and conductivity in compounds and produced inorganic ions during the course to degrade the model organic compound by 185 nm UV irradiation.

Key words: waste water, 4-chlorophenol(4-CP), 4-nitrophenol(4-NP), rhodamine B(Rh B), degradation, total organic carbon, 185 nm UV irradiation
