摘要：
Ion exchange and overoverequivalent sorption in the AV-17-2P-OH-Cl–tryptophan anion-exchange system are studied. It is established that the ion exchange of tryptophan against the background of the exchange of mineral ions (ОН––Сl–) is better accomplished from alkaline solutions on the Cl– form of the adsorbent and the overequivalent adsorption of an amino acid from a salt-containing solution on the OH– form of the anion exchange resin. The results from calculating and analyzing the thermodynamic constants of ion exchange and non-exchange absorption are given.
