The reaction conditions namely ratios of reagent to polymer and reaction time were investigated for high cation exchange capacity. The home-made sulfonated material was sucessfully used as solid phase extraction (SPE) sorbent with high static capacity (10 meqv/g), dynamic capacity ( meqv/g), fast mass transfer, and high enrichment factor. | Sulfonated hypercrosslinked adsorbent – synthesis and application in analytical chemistry
