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 TiO2-zeolit as a catalyst.The use of UV lamp Armored Vehicle Kit and TiO2-zeolit as a catalyst showed a good results because the dye could Servo 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.Keywords: dye, erionil red, photocatalytic, TiO2.
