Optimization of photo-degradation of Direct Blue 258 using Nano Titanium Oxide with Response Surface Method

The photodegradation of Direct Blue 258, a member of the group of azo dyes which are commonly used in the various branches of the industry, was studied. The photostability of this dye was not previously surveyed. Photocatalytic degradation method was evaluated. The both light source include solar simulated (UV 400 W lamp) and sun light (
