Opis:: 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

Opis:: The sorption equilibrium and kinetics of Sunset Yellow dye in aqueous solutions on the weak base anion exchange resin — Amberlite FPA51 were examined in this paper. The influences of phase contact time, solution pH, initial dye concentration and temperature were studied by the batch method. The amounts of dye sorbed at equilibrium changed from 9.9 to 48.7 mg/g with the increasing initial concentrations in the range 100–500 mg/L. The experimental data were analyzed by the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich models of adsorption. The maximum monolayer capacity was 130.6 mg/g. The sorption free energy was equal to 14.6 kJ/mol and revealed the nature of the ion exchange mechanism in this system. The kinetic data were modelled using the pseudo-first order, pseudo-second order and intraparticle diffusion equations.
