Sažetak
In this work, the influence of ionic strength of the solution on the adsorption of Reactive Black 5 dye on activated carbon was investigated. For this purpose, Reactive Black 5 dye solutions of concentration c0 = 500 mg dm3 with addition of 0.1 mole and 1.0 mole of sodium chloride was prepared. Sodium chloride is usually found in the bath for textile materials dyeing with reactive dyes. Isothermal adsorption was performed at 45 (±1) oC on 0.1 g of activated carbon in periods from 15 minutes to 16 hours (when equilibrium was reached). The obtained results were compared with an adsorption process carried out under the same experimental conditions, but without the addition of sodium chloride. It was shown that without the addition of salt 75 % of dye was adsorbed after 16 hours, while with addition of 0.1 mole and 1.0 mole of sodium chloride approximately the same percentage of dye was adsorbed after 30 minutes and less than 15 minutes, respectively. Thus, it was found that ionic strength of the solution significantly influences the adsorption process. The adsorption of both systems is kinetically controlled by the pseudo-second order kinetic model, while calculated pseudo-second order rate constant values further confirmed the obtained results.
