METHOD FOR REGENERATING ADSORBENT
Document Type and Number:
WIPO Patent Application WO/2002/068116
Kind Code:
A1
Abstract:
A method for regenerating an adsorbent having adsorbed a persistent substance, characterized in that the persistent substance is contacted with a microbe and/or an enzyme in the interior or at the periphery of pores of the adsorbent to thereby decompose the substance. The method allows an adsorbent having adsorbed a persistent substance, such as bis-phenols, harmful to living things to be completely decomposed and removed and thus allows the adsorbent to be regenerated, without adverse effect on the environment by secondary pollution.
