  • Materials for the solid/liquid extraction of heavy metal ions, containing supported N-functionalized polyazacycloalkanes
    Patent number: 8975395
    Abstract: The present invention relates to a material notably adapted for the extraction of metal cations in an aqueous medium, comprising a solid support on which are attached polyazacycloalkane compounds having a ring including at least 4 nitrogen atoms, and wherein the nitrogen atoms of the ring are substituted with coordinating groups, which each are independently: a coordinating group of formula: —(CH2)n—C(?O)—NR1R2 ?or else a both coordinating and binding group, fitting the formula: —(CH2)p—C(?O)—NR3-(A)-[support]. The invention also relates to methods for preparing the aforementioned materials and to different uses thereof, notably for the extraction of Pb2+ cations in an aqueous medium.
