THE USE OF TIO2-ZEOLIT AS A CATALYST ON THE DEGRADATION PROCESS OF ERIONIL RED DYE

Blog Article

Degradation of erionil red dye using photo catalytic processes with TiO2-zeolit as a catalyst was carried out.Degradation of the dye was observed in 10 L volume, and erionil red dye was used as a model of organic pollutant.The parameters examinated were intensity of the spectrum, the decrease of pH, percentage of degradation, and the efectifity Assessment of the quality of the healing process in experimentally induced skin lesions treated with autologous platelet concentrate associated or unassociated with allogeneic mesenchymal stem cells: preliminary results in a large animal model TiO2-zeolit as a catalyst.The use of UV lamp and TiO2-zeolit as a catalyst showed a good results because the dye could be degraded.

This could be seen from the decreasing of the intensity of the spectrum 24 h after Implementation of an Animal Sporotrichosis Surveillance and Control Program, Southeastern Brazil illumination.The pH of erionil red increased from around 4 into 5.5 which is still acidic.Effectivity of TiO2 composit as a catalyst could be used only two times.

The compound resulted from degradation that could be detected using HPLC was oxalic acid.Keywords: dye, erionil red, photocatalytic, TiO2.
