Abstract
Ispitana je sorpcija bakrovih iona na sintetskom zeolitu NaX u ovisnosti o različitim početnim koncentracijama otopina bakrovog(II) klorida pri dvije različite temperature: 28°C i 31°C. Eksperiment je proveden u šaržnim reaktorima pri brzini miješanja od 200 okr min-1, u trajanju od 1,5 h. Uočeno je da ravnotežna količina sorbiranih bakrovih iona iz otopine bakrovog(II) klorida na zeolitu (qe) raste s povećanjem ravnotežne koncentracije bakrovih iona u otopini (ce) pri obje odabrane temperature provedbe eksperimenta. Također je uočeno da je za sve odabrane početne koncentracije količina sorbiranih bakrovih iona na zeolitu viša pri višoj odabranoj temperaturi što je posljedica smanjene efektivne veličine iona uzrokovane smanjenjem hidratacijskog omotača oko iona. Učinkovitost sorpcije bakrovih iona na zeolitu opada s porastom početne koncentracije bakrovih iona u otopini. Nadalje, uočava se i da je učinak sorpcije bakrovih iona na zeolitu NaX nešto viši ako se proces izvodi pri višoj temperaturi za sve početne koncentracije. Procjenom kvalitete slaganja sorpcijskih modela s eksperimentalnim podatcima, usporedbom izračunatih vrijednosti maksimuma kapaciteta sorpcije i eksperimentalno dobivenog te statističkih parametara RMSE i χ2, može se zaključiti da najbolje slaganje s eksperimentalnim podatcima pokazuje Langmuirova izoterma kod sorpcije bakrovih iona iz otopine bakrovog(II) klorida pri svim odabranim temperaturama provedbe procesa sorpcije.
Abstract (english)
The sorption of copper ions on synthetic zeolite NaX was tested depending on different initial concentrations of copper(II) chloride solutions at two different temperatures: 28°C and 31°C. The experiment was conducted in batch reactors at a mixing speed of 200 rpm for 1.5 hours. It was observed that the equilibrium amount of sorbed copper ions from the solution of copper(II) chloride on zeolite (qe) increases with the increase of the equilibrium concentration of copper ions in the solution (ce) at both selected temperatures of the experiment conducted. It was also observed that for all selected initial concentrations, the amount of sorbed copper ions on the zeolite is higher at a higher selected temperature, which is a consequence of the reduced effective size of the ions caused by the reduction of the hydration shell around the ions. The sorption efficiency of copper ions on zeolite decreases with the increase of the initial concentration of copper ions in the solution. Furthermore, the sorption efficiency of copper ions on zeolite NaX is higher if the process is performed at a higher temperature for all initial concentrations. By assessing the quality of the agreement of sorption models with experimental data, comparing the calculated values of the maximum sorption capacity with the experimentally obtained ones and the statistical parameters RMSE and χ2, it can be concluded that the best fitting with the experimental data is shown by the Langmuir isotherm for the sorption of copper ions from copper(II) chloride solution at all selected temperatures of the sorption process.
