In this work, the aryldiazonium salts radical addition method has been used successfully to anchor 8-hydroxyquinoline (8-HQ) moieties onto the surface of Amberlite XAD-4 beads. The nitroaniline aryldiazonium salt was generated (in-situ) and covalently grafted onto Amberlite XAD-4 by aid of...

General

Chelating resins based on immobilised oxines are attractive solid-phase extraction (SPE) materials in the analysis of trace metals from environmental samples. The most common immobilisation procedure for bonding oxines to silica supports is time-consuming and incompatible with “green chemistry”...
