DEGRADATION OF FAST GREEN FCF USING IMMOBILIZED PHOTO-FENTON REAGENT

Degradation of fast green FCF by Fe-pillared bentonite clay in presence of light has been carried out. The progress of the reaction was monitored spectrophotometrically. The effect of some parameters affecting the rate of reaction, such as pH, dye concentration, amount of Fe-pillared clay, amount of iron concentration, H2O2, light intensity, etc. has been studied. Kinetic studies show that this reaction follows pseudo-first order kinetics. A tentative mechanism for photo-Fenton degradation of fast green FCF has also been proposed.
