Abstract
U ovom je diplomskom radu ispitana adsorpcija kobaltovih iona na ljuskama pistacija u ovisnosti o različitim početnim koncentracijama otopina kobaltovih iona (3,543; 7,028; 10,061; 17,138 te 24,452 mmol dm -3 ) pri stalnoj temperaturi od 303 K, brzini miješanja od 200 okr min -1 , u trajanju od 96 h. Uočava se, na temelju dobivenih rezultata, eksponencijalan porast količine adsorbiranih kobaltovih iona na ljuskama pistacija ( qe ) s porastom početne koncentracije kobaltovih iona u otopini ( c0 ). Pri najvišoj odabranoj koncentraciji postignute su i maksimalna vrijednost količine adsorbiranih kobaltovih iona koja iznosi qe = 0,529 mmol g -1 i najviša učinkovitost adsorpcije kobaltovih iona koja iznosi 10,826%. Uzimajući u obzir izračunate vrijednosti za koeficijent korelacije R 2 može se zaključiti kako Langmuirov adsorpcijski model bolje opisuje adsorpciju kobaltovih iona na ljuskama pistacija od Freundlichovog adsorpcijskog modela.
Abstract (english)
In this diploma thesis, the adsorption of cobalt ions on pistachio shells was studied depending on different initial concentrations of cobalt ions solutions (3.543, 7.028, 10.061, 17.138 and 24.452 mmol dm -3 ) at a constant temperature of 303 K, a stirring speed of 200 rpm -1 for 96 h. Based on the results obtained, an exponential increase in the amount of adsorbed cobalt ions on pistachio shells ( qe ) with an increase in the initial concentration of cobalt ions in solution ( c0 ) was observed. At the highest selected concentration, the maximum value of the amount of adsorbed cobalt ions, with the value of qe = 0.529 mmol g -1 , and the highest adsorption efficiency of cobalt ions, with the value of 10.826%, were achieved. Taking the calculated values for the correlation coefficient R 2 into account, it can be concluded that the Langmuir adsorption model better describes the adsorption of cobalt ions on pistachio shells unlike the Freundlich adsorption model.
