popup.description2
The use of a digital light meter for monitoring the kinetics of degradation of colored substances in real time has been proposed. The effect of hydrogen peroxide on the efficiency of photodegradation has been studied in the presence of titanium dioxide, synthesized by low-temperature method, peroxide method and the method of reverse micelles. A method for increasing of the photocatalytic activity of rutile in the presence of hydrogen peroxide has been proposed (combined action of photocatalyst and H2O2 provides efficient decomposition of harmful organic compounds, in particular organic dyes). 3D-diagrams of degradation efficiency of organic dyes on the synthesized photocatalysts have been proposed. The influence of process time and H2O2 concentration on the degree of pollutants photodegradation is shown. The accelerating effect of H2O2 on the degradation efficiency is explained by the increased formation of •OH radicals.
