INVESTIGATION OF PHOTOCATALYTIC DEGRADATION OF METHYLENE BLUE OVER TITANIUM DIOXIDE IN SUSPENSIONS

Effects of initial concentration of methylene blue,pH value of solution,reaction temperature,loading of titanium dioxide and UV light intensity on photodegradation of methylene blue have been investigated.Mechanisms of the interactions between effecting factors and degradation of methylene blue were explained.Kinetics for photocatalytic degradation mainly involving initial concentration and temperature were also discussed.The results indicated that methylene blue could be degradated efficiently under the approximate conditions.
