Abstract

The invention discloses a high-molecular iron (III) chelating agent based on 3-hydroxyl-4-pyridinone compounds and a preparation method thereof. The method comprises the following steps: subjecting epoxy-group-containing glycidyl methacrylate to free radical polymerization so as to obtain poly(glycidyl methacrylate), then adding amine-group-containing 3-hydroxyl-4-pyridinone compounds and then carrying out ring-opening reaction with epoxy groups, and carrying out covalent attachment to a side chain of poly(glycidyl methacrylate) so as to obtain the high-molecular iron (III) chelating agent. The preparation method provided by the invention avoids other side reaction and has the advantages of mild reaction conditions, safe production, simple process, convenient purification, high yield (the maximum being 100%) and facilitation to industrial production. Meanwhile, the problems like insolubility, infusibility, small iron (III) chelate capacity of a conventional high-molecular iron (III) chelating agent are solved, wherein the maximum of the chelating capacity of a ferric ion can reach to 1196 [mu]mol / g.
