Application of ionic liquids for solid-phase extraction of trace elements.
That phosphonium-type ionic liquids (ILs) can be used for preparation of novel solid-phase extractants has been shown. The conditions of IL immobilization on the different matrices (polyacrilonitrile, Amberlite XAD-7, hyper cross-linked polystyrene, and multi-walled carbon nanotubes) were determined. The solid-phase extraction of Pt(IV) from 1-2 M HCl and Pu(IV) from 3 M HNO(3) has been investigated. The possibility of retaining ligands on the solid phases by means of ILs to prepare the complexing solid-phase extractants has been demonstrated.
