ABSTRACT
Degradation of malachite green oxalate (MGO) compounds has been carried out by ozonolysis
and photolysis methods with addition of ZnO-SnO2 as catalyst. MGO solution was analyzed by
a spectrophotometer UV/Vis at 250-650 nm. The results showed that ozonolysis process faster
than photolysis. 6 mg/L MGO can be degraded as much as 97.3% after irradiated with UV light
(369 nm) within 150 minutes with the addition of 0.020 g of ZnO-SnO2. Otherwise, 99.6% of 6
mg/L MGO can be degraded by ozonolysis process within 5 minutes by the addition of 0.025 g
of ZnO-SnO2. Analysis of the remaining MGO solution by reverse-phase HPLC showed
intermediate-substances peaks and peak height of MGO at a retention time of 3.18 min
decreased as the data obtained using a UV/Vis spectrophotometer.
Keywords: degradation, MGO, photolysis, ozonolysis, ZnO-SnO2
