Polymeric resins were synthesized by suspension polymerization on a pilot scale and packed in an acrylic column for use in a semi-industrial elution system, to study their behavior as adsorbents of oily water. The performance in removing benzene, toluene and xylene (BTX) was greater than 95.9 %, and the efficiency in retaining polyaromatic hydrocarbons (PAH) remained near 96.3 %.
