ddt - 1,1,1-三氯-2,2-双（4-氯苯）乙烷是一种广泛用于农业防治昆虫的农药。tcp - 2,4,6-三氯苯酚已在农药制剂中用作防腐剂、消毒剂和杀菌剂。由于DDT和TCP的化学结构稳定，其解毒非常困难。本研究首次将nabh4与Devarda合金的混合物应用于DDT和TCP的解毒。结果表明，DDT在100℃下脱氯率为94%，TCP在80℃下脱氯率为97%。二苯乙烷的存在表明滴滴涕已完全脱氯。苯的形成表明发生了强烈的还原反应。该方法效率高，成本效益好，可应用于工业级。
DDT—1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane—is a pesticide that has been widely used to control insects in agriculture. TCP—2,4,6-trichlorophenol—has been used in pesticide formulations as a preservative, disinfectant and antiseptic. Detoxification of DDT and TCP is very difficult due to their stable chemical structure. Here, a mixture of NaBH4and Devarda alloy was applied for the first time to detoxify DDT and TCP. Results show 94 % dechlorination of DDT at 100 °C and 97 % dechlorination of TCP at 80 °C. The presence of diphenyl ethane suggests the complete dechlorination of DDT. The formation of benzene suggests a strong reduction. The method is efficient, cost-effective and may be applied at the industrial-level.
