| 摘 要： | 二噁(左口右英)是一类剧毒有机氯化物,已被联合国环境署和世界卫生组织列为持久性有机污染物和一级致癌物质,能够对环境和人类的健康造成重大危害.脱氯降解是降低二噁毒性的有效途径.本文对二噁的光降解、热降解、生物降解和化学降解脱氯作了详尽的评述,比较了各种降解方法的优劣,指出多相催化加氢脱氯降解方法将是今后的发展方向.

| Abstract: | Polychlorinated dibenzo-p-dioxins/furans (dioxins) is a kind of important persistent organic pollutants (POPs) and carcinogen. Dechlorination is an efficient means to eliminate the toxicity of dioxins. A review with 72 references concerning degradation methods was given in this paper. These degradation methods include photodegradation, thermal dechlorination, biodegradation, chemical dechlorination and heterogeneously catalytic hydrodechlorination. The heterogeneously catalytic hydrodechlorination might be developed to an efficient technology to eliminate the toxicity of dioxins. |
