Abstract
U ovom je diplomskom radu ispitana adsorpcija bakrovih iona na ljuskama jaja u ovisnosti o različitim početnim koncentracijama otopina bakrovih iona (2,876 mmol dm-3, 5,415 mmol dm-3, 8,200 mmol dm-3, 11,091 mmol dm-3 te 14,524 mmol dm-3) pri stalnoj temperaturi od 308 K, brzini miješanja od 200 okr min-1, u trajanju od 7 dana na ljuskama jaja promjera d < 0,250 µm. Količina adsorbiranih bakrovih iona (qe) na ljuskama jaja raste s porastom početne koncentracije bakrovih iona te postiže najvišu vrijednost pri najvišoj odabranoj početnoj koncentraciji vodene otopine bakrovog(II) klorida dihidrata (qe = 2,828 mmol g-1). S porastom početne koncentracije bakrovih iona u otopini raste i učinkovitost adsorpcije te je za sve otopine dobivena vrijednost veća od 90 %. Najviša dobivena vrijednost učinkovitosti adsorpcije iznosi 97,354 % pri najvišoj odabranoj početnoj koncentraciji vodene otopine bakrovog(II) klorida dihidrata, c0 = 14,524 mmol dm-3. Iz dobivenih rezultata proizlazi da su ljuske jaja veoma dobar adsorbens za izdvajanje bakra kao teškog metala iz vodenih otopina.
Abstract (english)
In this diploma thesis, the adsorption of copper ions on egg shells was studied depending on the different initial concentrations of copper ion solutions (2.876 mmol dm-3, 5.415 mmol dm-3, 8.200 mmol dm-3, 11.091 mmol dm-3 and 14.524 mmol dm-3) at a constant temperature of 308 K, a stirring speed of 200 rpm-1 for 7 days on egg shells particles size of d <0.250 µm. The amount of copper ions adsorbed (qe) on egg shells increases with the increase of initial concentration of copper ions and reaches the highest value at the highest selected initial concentration of aqueous copper(II) chloride dihydrate solution (qe = 2,828 mmol g-1). With the increase of the initial concentration of copper ions in the solution, the adsorption efficiency increases, and for all solutions a value greater than 90 % was obtained. The highest adsorption efficiency value obtained was 97.354 % at the highest selected initial concentration of aqueous copper(II) chloride dihydrate solution, c0 = 14.524 mmol dm-3. The results show that egg shells are a very good adsorbent for copper removal as a heavy metal from aqueous solutions. Keywords: egg shells, adsorption, copper, spectrophotometry, FTIR.
