Abstract

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
