摘要：

This study examines the use of ozone and ozone/ultraviolet radiation treatments of a kraft bleach plant effluent proceeding from the bleaching stages for kraft pulp decolorization. An outline for the reaction is proposed in which the oxidizable compounds of the effluent are grouped into three classes: easily degradable colored compounds, colored compounds of difficult degradation, and uncolored compounds. The constants for the second-order reaction rate at 20 °C and the stoichiometric coefficient were determined. © 1990, American Chemical Society. All rights reserved.
