Abstract

When some disperse dye was decolored with oxidation power of ozone, the results in investigation of decoloration behavior with dye solution and its order of reaction and variation of TOC were as follow: 1. Order of decoloration for Some disperse dye is C.I. Disperse Blue 79>Blue 73> Red 343>Red 60>Blue 354>Yellow 42. 2. Velocity of decoloration for the all dyestuffs was the fastest when pH 3. 3. TOC was rapidly reduced between 10 min. and 20 min. 4. For the reduction of TOC ozone was needs many times as compared with decoloration of dyestuffs.
