M 600, Amberlite IRA 458, Amberlite IRA 958, and Purolite A 850 were used to
remove basic (blue 3), acid (orange 7, tartrazine, sunset yellow, allura red), reactive
(black 5, blue 21), and direct (yellow 50, blue 71, red 75) dyes from model and real
effluents of the textile industry (Wawrzkiewicz and Hubicki 2015; Wawrzkiewicz
et al. 2018, 2019; Wołowicz et al. 2018). Comparison of the anion exchange capacities for selected azo dyes such as acid orange 7, direct blue 71, and direct yellow 50
as well as reactive blue 5 determined by the static method is presented in Fig. 11.9
(Wawrzkiewicz and Hubicki 2015; Wawrzkiewicz et al. 2019). The vast majority of
