Rapid total Destruction of Chlorophenols by Activated Hydrogen Peroxide

摘要

A practical inexpensive, green chemical process for degrading environmental pollutants is greatly needed, especially for persistent chlorinated pollutants. Here we describe the activation of hydrogen peroxide by tetraamidomacrocylic Ligand (TAML) iron catalysts, to destroy the priority pollutants pentachloro- Phenol (PCP) and 2,4,6-trichlorophenol (TCP). In water, in minutes, under Ambient conditions of temperature and pressure, PCP and TCP are completely Destroyed at catalyst: substrate ratios of 1:715 and 1:2000, respectively. The Fate of about 90/100 of the carbon and about 99/100 of the chlorine has been Determined in each case. Neither dioxins nor any other toxic compounds are Detectable products, and the catalysts themselves show low toxicity.
