Abstract

Procedure for preparing coated active carbon particles, characterized in that in a first step a copolymer of a solution of acrylic acid-styrene or acrylic acid-acrylonitrile copolymer is prepared, which comprises approximately between 1 and 60 mol% of acrylic acid, and in a second stage, activated carbon particles are provided with a thin coating layer of the polymer obtained from the previous stage, thus leaving said activated carbon particles encapsulated in a hydrophilic charged polymeric film.
