Özet:

 

The equilibrium sorption isotherms of 3 reactive dyes (C. I.  Reactive Yellow 84, C. I. Reactive Red 141, C. I. Reactive Blue 160)  and their binary mixtures adsorbed on prewetted wool fiber were  investigated.  The kinetic studies were carried out at pH \le 7 and 80  °C in dye solutions containing 20 g/L NaCl.  It was reported that  binary mixtures of these reactive dyes have lower sorption values than  the dyes alone, at the same dye concentration, pH and temperature.   The isotherms obtained are Langmuir type.  The rate parameters of  adsorption kinetics decrease with increasing dye concentration.
