Abstract
ABSTRACT THE DEGRADATION OF A COMPOUND CARBARYL IN AN INSECTICIDE SEVIN® 85SP IN OZONOLYSIS BY THE ADDITION OF TiO2/ZEOLIT by: PRIMA NUANSA (BP : 0810411003) Dr. Zilfa, MS dan Prof. Dr. Hamzar Suyani, M.Sc An investigation of carbaryl degradation 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. Spectrophotometric analysis showed the reduction of carbaryl absorbance after degradation occurred. Degradation of 10 mL carbaryl 15 mg/L without addition of catalyst by ozonolysis was reached 42.14% after 60 minutes. Degradation percentages of 10 mL carbaryl (15 mg/L) with additions of 15 mg TiO2/Zeolit was 56.67% after 60 minutes. Whereas with addition of 0.6 mg TiO2-anatase percentage degradation reach 50.10% during ozonolysis 60 minutes and with addition of 14.4 mg zeolite, percentage degradation reach 23.72% during ozonolysis 60 minutes. The result proved that TiO2/Zeolit was an effective catalyst in carbaryl degradation by ozonolysis method. Keywords : degradation, carbaryl, ozonolysis, TiO2/Zeolit
