【Abstract】 A new method for rapid dechlorination of trichloroethylene (TCE) in water is presented. The method, dechlorination of trichloroethylene by Pd/Fe 0, is proved to be very effective. In optimal condition, the dechlorination efficiency is nearly 100% in 10 minutes. Some factors which are related with dechlorination efficiency and the dechlorination mechanism are also discussed.更多还原
