Abstract
U ovom je diplomskom radu ispitana adsorpcija niklovih iona na ljuskama jaja u ovisnosti o različitim početnim koncentracijama otopina niklovih iona (3,922; 9,885; 13,139; 20,411 30,327 mmol dm-3) pri stalnoj temperaturi od 308 K, brzini miješanja od 200 okr min-1, u trajanju od 96 h. Na temelju dobivenih rezultata može se zaključiti kako količina adsorbiranih niklovih iona (qe) raste s porastom početne koncentracije niklovih iona u otopini (c0) postižući maksimalnu vrijednost pri najvišoj odabranoj koncentraciji te iznosi qe = 0,337 mmol g-1. Učinkovitost adsorpcije niklovih iona dostiže svoju maksimalnu vrijednost pri početnoj koncentraciji od 13,139 mmol dm-3 te iznosi 6,911%. Uzimajući u obzir izračunate vrijednosti za koeficijent korelacije R2 može se zaključiti kako se adsorpcija niklovih iona na ljuskama jaja najbolje može opisati Langmuirovim adsorpcijskim modelom.
Abstract (english)
In this diploma thesis the adsorption of nickel ions on egg shells was studied depending on the different initial concentrations of nickel ions solutions (3.922, 9.885, 13.139, 20.411 and 30.327 mmol dm-3) at a constant temperature of 308 K, stirring speed of 200 rpm for 96 h. Based on the results obtained, it can be concluded that the amount of adsorbed nickel ions (qe) increases with the increase of the initial concentration of nickel ions in solution (c0) reaching its maximum value of qe = 0.337 mmol g-1 at the highest selected concentration. The adsorption efficiency of nickel ions reaches its maximum value of 6.911% at initial concentration of 13.139 mmol dm-3. Taking into account the calculated values of the correlation coefficient R2 it can be concluded that the adsorption of nickel ions on egg shells can best be described by the Langmuir adsorption model.
