The weakly basic anion exchangers of the functional tertiary amine gropus with the polystyrene skeleton: Amberlyst A-21 and with acrylic skeleton: Amberlite IRA-67 were investigated as adsorbents of Remazol Black B from aqueous solutions. Experiments were carried out as function of contact time (1–240 min.), initial dye concentration (50–500 mg/dm3), pH (1–12), temperature (298–318 K) and ionic strength (NaCl). The results indicate that the investigated anion exhchangers are suitab;e as adsorbent material of Remazol Black B from aqueous solutions
