Polymer Chemistry

The preparation of polymers modified with ion-selective ligands allows for their utilization in areas where toxic metal ions must be removed from water in the environment in order to be rendered safe. The modification of polystyrene beads with glucamine ligands has led to an arsenic-selective resin, modification with phosphonic acid ligands has led to an actinide-selective resin, and modification with phosphonate ligands has led to a lead-selective resin. The ability of auxiliary groups to modify the ionic selectivity of a primary ligand is the subject of current research.
