Abstract:
Polynuclear aromatic compounds are irreversibly adsorbed by coconut charcoal and are separated from desired constituents by treatment in a coconut charcoal column. This invention is particularly valuable in providing a method suitable for large scale use for removing dioxins and other undesirable polynuclear aromatic hydrocarbons which are found as impurities in small but highly toxic amounts in industrial compounds and herbicides such as 2,4,5-T, 2,4-D and derivatives thereof.
