Method for removing polychlorinated dibenzodioxins and polychlorinated dibenzofurans from secondary fibers using supercritical CO2 extraction |
| abstract |
A process for removing PCDD's and PCDF's from cellulose-containing fibers such as waste paper is provided. The process comprises contacting the fibers with supercritical or near supercritical carbon dioxide for a period of time sufficient to extract a substantial portion of the PCDD's and PCDF's without substantially damaging the fibers. Extraction efficiencies of greater than 95% have been achieved with the technique. |
