METHOD FOR REMOVAL, SEPARATION OR DEGRADATION OF PERSISTENT ORGANIC POLLUTANTS FROM A SUBSTRATE

摘要

The present invention relates to a method for removal, separation or degradation of one or more persistent organic pollutant(s) (POPs) present in a substrate, the method comprising(i) the provision of a POP-contaminated substrate; (ii) a first reaction stage comprising adding to the substrate a basic solution (solution 1), and optionally one or more additives selected from the group comprising a transphase catalyst (TPC) and a hydrogen peroxide dissociation catalyst, and incubating the substrate with solution 1 and optionally the one or more additives for at least 5 minutes; and (iii) a second reaction stage comprising adding to the substrate a hydrogen peroxide solution (solution 2) and optionally one or more additives selected from the group comprising a TPC and a hydrogen peroxide dissociation catalyst, wherein a hydrogen peroxide dissociation catalyst and a TPC are added during the first and/or the second reaction stage.
