Penggunaan Komposit Sebagai Katalis Dalam Proses Penguraian Zat Warna Erionil Red
ABSTRACT: 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 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 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.
