Sažetak/Abstract: 

Adsorpcijska kinetika predstavlja važan korak u istraživanju adsorpcijskih sustava. U ovom radu proučavana je kinetika adsorpcijskog sustava otpadna kalupna mješavina/Cu (II) ioni. Za opis kinetike korišteni su sljedeći modeli: pseudo prvi i drugi red, Elovichev model i unutarčestična difuzija. Dobiveni rezultati pokazali su da se kinetika adsorpcije Cu (II) iona na otpadnoj kalupnoj mješavini odvija prema kinetičkom modelu pseudo drugog reda.

 

Adsorption kinetics is an important step in the study of adsorption systems. The paper studies adsorption process kinetics of the waste mould sand/Cu(II) ion system. For description of the kinetics, the following models were used: the pseudo-first and pseudo-second order, Elovich model, external diffusion and intraparticle diffusion. The obtained results show that the kinetics of Cu (II) ion adsorption on the waste mould sand takes place according to the kinetic model of the pseudo-second order.
