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 Bun pH, percentage of degradation, and the efectifity TiO2-zeolit as a catalyst.
The use of UV lamp and TiO2-zeolit as a catalyst showed a good results because Tape the dye could be degraded.This could be seen from the decreasing of the intensity of the spectrum 24 h after 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.
