COMPOSITE ELEMENT INCORPORATING A POLYETHER OR COPOLYETHER, ITS PREPARATION PROCESS AND ITS USE FOR EXTRACTING AND SEPARATING METAL CATIONS

摘要

DESCRIPTIVE The invention relates to a composite element incorporating a support of an organic, electricity conducting, polyaromatic structure product, such as graphite, covered with a polymer or copolymer of dibenzoethers of formula: (I) and/or (II) in which m=0 or 1 to 10, n=0 or 1 to 10, m+n ?10, p=o or 1 to 6, R1=alkyl or aryl, R2=alkyl or aryl. These elements are usable for absorbing metal cations present in an aqueous or organic solution. B 10 024 MDT
