Zusammenfassung: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.
