Adsorption of reactive dyes and surfactants onto chitin from mixtures containing surfactants at constant concentration and dyes at variable concentration was investigated in the present study. Two vinylsulfonate dyes (Scarlet R, Brillantorange 3R); chlorotriazine dye (Black DN); anionic (Borutosol KRN, Siarczanol N-2) and non-ionic (Rokafenol N-8) surfactants were tested. The experiments were carried...
The effect of chitin preparation with HCl (chitin A) and with HCl and KOH (chitin B) and pH on the adsorption of reactive dyes (helactine, polactine and remazol) on chitin was investigated. The double Lang- muir equation was appropriate to analyze the dependence between amount of the adsorbed dye on chitin (Q) and its equilibrium concentration (C). It indicated the presence of two types of active...
