Abstract

In this study, a metal organic framework based on the Ti (MIL-125) was synthesized by the hydrothermal method and characterized using XRD, SEM and DRS. The photocatalytic activity of synthesized MIL-125 was evaluated in photocatalytic degradation of Reactive blue 19 as an organic pollutant. The degradation efficiency was more than 90% confirming photocatalytic activity of synthesized MIL-125. The kinetics of photocatalytic reactions of MIL-125 were also studied. The results of experiments showed pseudo first-order kinetics for photocatalytic process by MIL-125. Based on the first-order kinetics, the empirical kinetic model was developed to predict the rate constant and degradation efficiency. There is a good agreement between the calculated apparent rate constants and experimental ones.
