Modeling Degradation of Dye Molecules into Water, and Light Molecular and Gaseous Components
An experimental model using only bijective functions was designed to describe the dye degradation of three dyes: C.I. Reactive Blue 19, C.I. Reactive Black 5, and C.I. Reactive Red 120. The experimental model was compared to a theoretical predictive exponential decay model based on the principles of Fick's first law of diffusion. The models agreed within a range of 3 to 35% for the Reactive Blue 19 experiments, 1 to 9% for the Reactive Black 5 experiments, and 1 to 15% for the Reactive Red 120 experiments, with tighter fits at higher rates and concentrations. A 25% increase in the volume of solvent used only decreased the residence times of the reaction by 0.9%, 0.6%, and 5.3%, respectively.
