【Abstract】 An energy transfer photochemical model for the abatement of total organic carbon(TOC)in high purity water using 185nm Ultraviolet(UV)irradiations is proposed.The dependence of 185nm UV irradiation energy on the water flow rates,TOC concentrations and size of irradiation cell has been established.The models of selection of 185nm UV source and calculation in engineering design have been solved.The theoretical calculation agrees with experiments,which proves the model to be correct.The TOC concentrations in high purity water were decreased from 4200μg/L to 0.3μg/L,which is the lowest concentration of TOC.更多还原
