DEGRADASI SENYAWA KARBARIL DALAM INSEKTISIDA SEVIN® 85SP SECARA OZONOLISIS DENGAN PENAMBAHAN TiO2/ZEOLIT
Abstract: An investigation
of carbaryl degradation
contained in insecticide
Sevin® 85SP by
ozonolysis has been performed.
Ozonolysis is one of many
degradation methods for
organic compound by
using ozone (O3) that breaks the bond between C=C to produce the C=O
bond. The result of degradation were detected by UV-Vis spectrophotometer at a
wavelength of 280 nm. Spectrophotometry analysis showed the reduction of
carbaryl absorbance after degradation occurred. Carbaryl diluted in volume of solvent
acetonitril : water
= 6 :
4. Degradation of
10 mL carbaryl
15 mg/L without
addition of catalyst by
ozonolysis was reached 42.14% after 60 minutes. Although degradation
percentages of 10 mL carbaryl (15 mg/L) with additions of 15 mg TiO2/Zeolit was
56.62% after 60 minutes. The result proved that TiO2/Zeolit was an effective
catalyst in carbaryl degradation by ozonolysis method.
