An adsorbent from corn stalks by their modification with polyaniline has been obtained. Ad-sorption properties of this adsorbent have been studied for removal anionic dyes (Acid Red, Acid Orange and Direct Claret). It was established that polyaniline modified corn stalks may be an effective low-cost adsorbent for the removal of anionic dyes from aqueous solutions in the pH range from 2 to 6, and the optimal adsorbent dosage is 10 g/L. Adsorption kinetic curves are well described by the kinetic equation of pseudo-second order.
