摘要： The invention provides a process for preparing polymer beads incorporating magnetic iron oxide particles, which process comprises producing a dispersion having a continuous aqueous phase and a dispersed organic phase, the organic phase comprising one or more polymerisable monomers, magnetic iron oxide particles and an organophosphorus dispersing agent for dispersing the magnetic iron oxide particles in the organic phase, and polymerising the one or more polymerisable monomers to form the polymer beads incorporating the magnetic iron oxide particles; complexing and ion exchange resins prepared by this process; methods for separating transition metal ions and other ions from an aqueous solution using the complexing and ion exchange resins; and polymer beads comprising a polymeric matrix having magnetic iron oxide particles and organophosphorus dispersing agent dispersed substantially uniformly therein.

摘要： The invention provides a process for preparing polymeric beads of complexing resin incorporating magnetic particles, which process comprises: producing a dispersion having a continuous aqueous phase and a dispersed organic phase, said organic phase comprising one or more polymerisable monomers, magnetic particles and a dispersing agent for dispersing said magnetic particles in the organic phase; polymerising said one or more polymerisable monomers to form polymeric beads incorporating said magnetic particles, wherein said polymeric beads include amine groups capable of complexing a transition metal cation, or wherein said polymeric beads are reacted with one or more compounds to provide amine groups capable of complexing a transition metal cation, complexing resins prepared by this process, and polymeric beads of complexing resin comprising a polymer matrix having magnetic particles dispersed substantially uniformly therein, wherein the polymer matrix incorporates amine groups capable of complexing a transition metal cation.
