Chloroorganic compounds (e.g., chlorophenols, chlorobenzenes and chloroanilines) are widely used as solvents, fungicides and as major intermediates for various manufacturing processes. These compounds are very toxic and their toxicity tends to increase with their degree of chlorination. Many of the these compounds tend to persist in the environment and pose potential health risk. Anaerobic dechlorination of chlorobenzenes, chlorophenols and chloroanilines have been well documented. For example, two researchers have examined the dechlorination of 3,4,5-TCP and identified its metabolites and pathway of degradation. Similarly, Wang and Jones and others have reported on the dechlorination of chlorobenzenes, while Kuhn and Suflita have reported on the transformation of chloroanilines in sediments. However, in all these studies, information on the kinetics of transformations are very limited and very few reports have been published on the modeling of dechlorination reactions. The objective of this study was to model the sequential dechlorination of 1,2,3-TCB, 3,4,5-TCP and 3,4,5-TCA using a first order reaction kinetics. 12 refs., 2 figs., 2 tabs.
