Özet:

 

The adsorption behavior of crystal violet (CV) from aqueous  solution onto bottom ash was investigated under various experimental  conditions.  The parameters studied included contact time, initial CV  concentration, particle size, and ionic strength.  The kinetic  experimental data were analyzed by different models.  The experimental  adsorption data showed good correlation with the kinetic models and  suggested a multimechanism sorption process.  The adsorption  mechanisms follow pseudo-second-order kinetics with a significant  contribution of intraparticle diffusion and film diffusion.  Pseudosecondorder kinetics follows the removal of CV by bottom ash for  smaller particle size (150 m m.  The adsorption  mechanism was further analyzed by Reichenberg's method.  The  adsorption capacity of bottom ash decreases with increases in CV  concentration and increases with particle size.  The effect of ionic  strength was analyzed by adding NaCl and CaCl2.  The ionic strength  variation study showed that CV removal increases with increases in  NaCl and CaCl2 concentration.
