Potential Degradation of Toxaphene by Iron Dechlorination

0207061 Clark研究的目的是调查降解或销毁持久性氯化污染物的新方法的可行性。 这项探索性研究将集中于毒杀芬，这是一种1990年被禁止的农药，有毒，很难降解。 毒杀芬是200多种多氯萜烯的复杂混合物。 这项研究将审查毒杀芬通过零价铁和其他可降解基质的脱氯作用，以此作为启动其降解的一种手段。 实验拟确定毒杀芬的降解率由铁基板，毒杀芬脱氯的潜在途径，并为这一进程的潜在速率限制因素。 这些初步结果将用于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. ***
