Kinetic modeling on photo oxidative degradation of C.I acid yellow 23 by UV/H_2 O_2 process
نویسندگان
چکیده مقاله:
The kinetic of photo oxidative decolorization of C.I. Acid yellow 23 (AY23) was investigated in UV/ process. The semi-logarithmic of the concentrations of AY23 versus irradiation time were linear, suggesting pseudo-first order reaction. A simple kinetic model is proposed which confirms pseudo- first order reaction. The results indicate that the apparent reaction rate constant is a function of light intensity, and AY23 initial concentrations. These results are in good agreement with proposed kinetic model.

متن کاملKinetic study on the electrodecolorization of C.I. Acid Yellow 23
The electrocoagulation (EC) is a simple and efficient method for the treatment of many water and wastewaters.The kinetics of decolorization of Acid Yellow 23 by EC using iron electrodes was studied. Theelectrodecolorization rate follows pseudo-first order kinetic with respect to the AY23 concentration havingkapp= 5.65 cm min-1 at T= 295 K. The rate equation is as follows:ln [AY23]t – ln [AY23]0...

متن کاملPhoto-oxidative degradation of Direct Yellow 12 using hydrogen peroxide
The photo-oxidation process by combination of UV light and H20 2 generates hydroxyl radicals which are capable of oxidising many organic compounds which are refractory type and difficult to oxidize by conve nt ional' chemical treatment. In the present study, photo-oxidation of Direct Yellow 12 (DY 12) dye has been carri ed out in an annular type photoreactor using 8 Watt low pressure mercury la...
