Process for collecting and separating of water-insoluble pollutant from aqueous or soil environments, and adsorbent composition utilized therein

摘要

The present invention relates to a process for collecting and separating of water-insoluble pollutant from aqueous or soil environments, comprising the steps of: (i) applying an adsorbent composition comprising chitin, chitosan or derivatives thereof and at least one anionic surfactant to the aqueous or soil environment polluted with water-insoluble pollutant, so that the polymer having pollutant entrapped therein is coagulated, and (ii) separating the coagulated polymer from the aqueous or soil environment; and an absorbent composition utilized in that process.
