Abstract
Ispitana je adsorpcija bakrovih iona na humusu u ovisnosti o početnim koncentracijama otopina bakrovih iona (5,255 mmol dm-3, 10,081 mmol dm-3, 12,175 mmol dm-3, 23,325 mmol dm-3 te 38,181 mmol dm-3). Eksperiment je proveden pri stalnoj temperaturi od 318 K, brzini miješanja od 200 okr min-1 te trajanju eksperimenta od 96 h. Na temelju dobivenih rezultata može se zaključiti kako se količina adsorbiranih bakrovih iona (qe) neznatno mijenja porastom početne koncentracije bakrovih iona u otopini (c0), a svoju maksimalnu vrijednost dostiže pri početnoj koncentraciji od 38,181 mmol dm-3 te iznosi qe = 0,529 mmol g-1 za uvjete pri kojima je eksperiment proveden. Učinkovitost adsorpcije bakrovih iona dostiže svoju maksimalnu vrijednost za najnižu odabranu početnu koncentraciju od 5,255 mmol dm-3 te iznosi 48,032 %, a nakon toga opada porastom početne koncentracije bakrovih iona u otopini. Uzimajući u obzir kvalitetu slaganja adsorpcijskih modela s podatcima koji su dobiveni eksperimentalnim putem, kao i usporedbom izračunatih vrijednosti maksimuma kapaciteta adsorpcije bakrovih iona s onima eksperimentalno dobivenim te statističkim parametrima za RMSE, χ2 može se zaključiti da najbolje slaganje s eksperimentalnim podatcima pokazuje Tothova adsorpcijska izoterma.
Abstract (english)
The adsorption of copper ions on humus was studied depending on the different initial concentrations of copper solutions (5.255 mmol dm-3, 10.081 mmol dm-3, 12.175 mmol dm-3, 23.255 mmol dm-3, 38.181 mmol dm-3). The experiment has been carried out at a constant temperature of 318 K, stirring speed of 200 rpm for duration of 96 h. Based on the results obtained, it can be concluded that the amount of copper ions adsorbed (qe) changes slightly with the increase of the initial concentration of copper ions in solution (c0), reaching its maximum value at an initial concentration of 38.181 mmol dm-3 with the value of qe = 0.529 mmol g-1 for the conditions under which the experiment was conducted. The copper adsorption efficiency reaches its maximum value for the lowest selected initial concentration of 5.255 mmol dm-3, with the value of 48.032 % and then decreases with the increase of the initial concentration of copper ions in solutions. Considering the quality of the agreement of the adsorption models with the data obtained experimentally, as well as the comparison of the calculated values of the maximum adsorption capacity of copper ions with those obtained experimentally and the statistical parameters for RMSE, χ2 as well it can be concluded that the best agreement with the experimental data is shown by Toth’s adsorption isotherm.
