Decolorization and Mineralization of Cationic Dye (Crystal Violet) by Several Photochemical Methods.

摘要

ABSTRACT The aim of this study is to test the ability of some photochemical processes advanced oxidation processes (AOPs) such as: UV/H2O2, UV/S2O82- to eliminate dye in aqueous solution. The efficiency of substrate decolorization and mineralization in each process has been comparatively discussed by decreases in concentration and total chemical oxygen demand content of CV solutions. The obtained results showed that system like: H2O2/UV and S2O82- /UV were better than direct UV photolysis at.254.
