ABSTRACT
Batch degradation studies were conducted with soil inoculum, collected from the contaminated site, spiked with aqueous sulfolane and stirred under anaerobic conditions. The results of the study show that sullblune was degraded tip to 64% alter 6X d of incubation time for initial concentration of 6 6 mmol I 1 in the absence of nutrients. Ileadspace analyses indicate that approximate!) 1 mmol I carbon for the sulfolane (26 mmol I ' carbon) fully degrades to CH4 CO as the ultimate products. The rest of the degraded sullblune presents as unidentified intermediate aqueous products. Sulfur balance indicates that approximately 94% of sulfur still remained in the reactor while hydrogen sulfur was observed at 2.5 mg I'' in the head-space.
