Design and controllable synthesis of ethylenediamine-grafted ion imprinted magnetic polymers for highly selective adsorption to perchlorate.

A series of ethylenediamine-grafted ion imprinted magnetic polymers (FeO@IIPs) were synthesized ultrasonic assisted suspension polymerization with perchlorate (ClO ) as an ion imprinting template. They were characterized by XRD, EA, VSM, FTIR and XPS and applied as adsorbents for ClO removal from aqueous solutions. The effects of the usage amount of crosslinking agent divinylbenzene (DVB) used for preparation on the structure and the adsorptive performance of FeO@IIPs were investigated.
