Use of crosslinked poly(ferric acrylate) as a sorbent in solid-phase extraction
A sample-preparation step, before chromatographic analysis, is frequently performed to enrich the components of interest from a complex matrix. This step is also needed to purify and concentrate the analyte present in a highly dilute medium. Solid-phase extraction (SPE) with a specific sorbent is one of the most widely used techniques for extracting trace components from aqueous or nonaqueous media. In this method, analytes are extracted by the passage of the medium through a cartridge containing a solid matrix. The recovery of the analytes from the medium considerably depends on the extent of the interactions between the analytes and the sorbent. Through the enhancement of these interactions, the extent of the uptake of the analytes can be improved. Poly(acrylic acid) is commonly employed as the sorbent in SPE for the isolation of polar analytes. This article discusses the use of the metal-containing polymer poly(ferric acrylate) as the sorbent for the isolation of a few phenols as representative components from water. The results indicate that the metal-containing polymer has an enhanced adsorption capacity in comparison with the capacity of the widely used sorbent poly(acrylic acid).
