The invention provides a metal chelate resin that comprises repeating units having the structure:
1
where M is a metal ion in an oxidation state capable of forming a complex with a tetradentate ligand having an overall coordination number of at least 6, R1, R2, R3, R4 and R5 are each hydrogen, halogen, straight-chain or branched alkyl, or alkenyl having 1 to 4 carbon atoms, halogenoalkyl having 1 or 2 carbon atoms and 1 to 5 fluorine, chlorine and/or bromine atoms, straight-chain or branched alkoxyalkyl having 1 to 3 carbon atoms in the alkoxy moiety and 1 to 3 carbon atoms in the alkyl moiety, alkylcarbonyl having 1 to 4 carbon atoms in the straight-chain or branched alkyl moiety, phenyl, or phenylcarbonyl, it being possible for each of the above mentioned phenyl radicals to be mono- to tri-substituted by identical or different substituents from the group consisting of fluorine, chlorine, bromine, cyano, nitro, alkyl having 1 or 2 carbon atoms, alkoxy having 1 or 2 carbon atoms, alkylthio having 1 or 2 carbon atoms, halogenoalkyl having 1 or 2 carbon atoms and 1 to 5 fluorine, chlorine and/or bromine atoms, halogenoalkoxy having 1 or 2 carbon atoms and 1 to 5 fluorine, chlorine and/or bromine atoms, halogenoalkylthio having 1 or 2 carbon atoms and 1 to 5 fluorine, chlorine and/or bromine atoms, provided that if R2, R3, R4 and R5 are all hydrogen R1 may not be hydrogen, R6 is a linking arm connecting the nitrogen atom of the ligand with R7 where R7 is a functional linking group through which the R6 linking arm is connected to R8 and R8 is an insoluble immobilization matix.
