Potential Degradation of Toxaphene by Iron Dechlorination

0207061克拉克：这项研究的目的是探索降解或销毁持久性氯化污染物的新方法的可行性。这项探索性研究将重点放在毒杀芬上，这是一种1990年被禁用的杀虫剂，它有毒，非常难以降解。毒杀芬是一种由200多种多氯萜烯组成的复杂混合物。这项研究将考察零价铁和其他双金属底物对毒杀芬的脱氯作用，以此作为启动毒杀芬降解的一种手段。通过实验确定了毒杀芬在铁基质上的降解速率，毒杀芬脱氯的可能途径，以及该过程的潜在速率限制因素。这些初步结果将被用来寻求实验程序的变化和脱氯实验的优化。***

0207061 Clark The objective of the research is to investigate the feasibility of new methods to degrade or destroy persistent chlorinated contaminants. This exploratory research will focus on the toxaphene, a pesticide banned in 1990, which is toxic and very difficult to degrade. Toxaphene is a complex mixture of more than 200 polychlorinated terpenes. This research will examine the dechlorination of toxaphene by zero-valent iron and other bimetallic substrates as a means to initiate its degradation. Experiments are proposed to determine the degradation rates of toxaphene by iron substrates, potential pathways of toxaphene dechlorination, and the potential rate limiting factors for this process. These preliminary results would be used to seek variations in experimental procedures and optimization of the dechlorination experiments. ***
