Kinetics and Identification of Products Degradation of Endosulfan in a Solution of Carbofuran by Hydrolysis, Ozonation with and Without Activated Carbon

Enjarlis and Ratnawati

Abstract—Degradation of endosulfan in the solution carbofuran by hydrolysis, ozonation with and without activated carbon is investigated at fixed initial concentration, temperature and neutral pH. The objectives of this research were to study the effect of hydrolysis, ozonation with and without activated carbon on degradation rate of single endosulfan and endosulfan in the carbofuran solution as well as to identify products by ozonation. The hydrolysis process slightly influences in enhancing degradation rate of endosulfan compared to ozonation processes without and with of activated carbon. The ozonation with activated carbon for endosulfan in carbofuran solution significantly influences in enhancing degradation rate compared to single endosulfan. From gas chromatography-mass spectrometry (GC/MS) analysis showed that the four products obtain from the degradation of endosulfan in carbofuran solution by ozonation without activated carbon are carbofuran-phenol, endodiol, 4,5,6,7,8,8-hexakhloro-1, 3 , 3a, 4,7,7 a-hexahydro-allosa and Azelaoyl Cloride. Whereas, producs ozonation with activated carbon generate 1,4,5,6,7,-hexachlorobicyclo [2,2,1-5-heptene-2, 3-dimetanol (HBH), azelaic acid (AA), azelaoyl chloride ( AC), S-[2-(dimethyl amino) ester (SDAE) and methyl 4-methylphenylsulfoxide (MMPs) after 15 minute process.

Index Terms—Activated carbon, Degradation rate, hydrolysis, Ozonation.
