Procedures are described to prepare γ‐aminobutyrohydroxamate resin and its N‐methyl and O‐methyl derivatives. With the aid of a chemical method, IR and electronic spectra, and potentiometry, the chelating properties of these resins are compared with each other. The selectivity of resins for various metals is expected to be comparable to complexing properties of a monomer having a structure similar to that of active groups. This correlation was made quantitatively by measurement of metal capacity, fraction of sorption, pH and period for extraction of half the metal ions, stability constants etc. Not only γ‐aminobutyrohydroxamate resin but also its N‐methyl and O‐methyl derivatives exhibit much potential for application in chelation ion chromatography.
