DEGRADASI MALACHITE GREEN OXALATE SECARA FOTOLISIS DAN OZONOLISIS DENGAN PENAMBAHAN ZnO-SnO2
ABSTRACT: Degradation of
malachite green oxalate (MGO) compounds has been carried out by ozonolysis and
photolysis methods with addition of ZnO-SnO 2 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-SnO 2 . 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.
