<p><P>PROBLEM TO BE SOLVED: To take out residual organic pollutants offered to supercritical hydroxylation by removing mineral particulates from waste mixed with the mineral particulates and residual organic pollutants. <P>SOLUTION: A method for separating the residual organic pollutants from waste containing one or a plurality of residual organic pollutants and non-water-soluble mineral particulates performs a mixing step (step S102) mixing a waste material, a nitrate aqueous solution and a surfactant, a settlement step (step S103) being settled thereafter and a picking step (step S104) separating a phase containing the mineral particulates and a phase containing the residual organic pollutants from a plurality of phases separated by the settlement step (step S103) and picking them. The phase containing the mineral particulates is further subjected to a mixing step (step S106), a settlement step (step S107) and a picking step (step S108) to remove the residual organic pollutants mixed in the mineral particulates. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
