Özet:

 


In
this study, the factors influencing the rate of chemical oxygen demand (COD) of
a synthetic waste solutions containing water soluble reactive dye [Reactive
Yellow 17 (RY17)] by ozone gas was investigated. The research was conducted
using a semi-batch bubble column to take the advantage of the intensive
back-mixing that prevails in bubble columns. As a result, the COD of disperse
dyestuff wastewater was reduced to 78.58%, and decolorization was remarkable
under the basic condition of pH
12, complete each dye degradation occurs in 12 min, ozone consumption goes on for a further 30 min after which time most
degradation reaction is completed. Kinetic studies were exhibited that direct
ozonation of the aqueous dyes were a pseudo-first-order reaction with respect
to the dyes. The apparent rate constant increased with both applied ozone dose
and higher pH values, declined logarithmically with the initial dye
concentration.
