Synthesis of Polymeric Sorbents with Magnetic Properties

In this work, a procedure for the synthesis of polymeric sorbents based on hypercrosslinked polystyrene (HPS) with magnetic properties was developed. The technique is based on the reduction of iron salts with polyhydric alcohols at high temperature in an inert atmosphere. The resulting sorbents retain their original characteristics: an extended specific surface area, micro-mesoporous structure, acquiring magnetic properties, which makes it possible to use them as magnetically separable sorbents, supports for the active phase of heterogeneous catalytic systems etc.
