Abstract
Ovim je radom obuhvaćena priprava, nanošenje i testiranje membrane selektivne za kalijeve ione. Također, testiran je pretvornički sloj grafit:polivinil butiral (PVB) različitih masenih udjela grafita koji se nanosi kao međusloj između membrane i elektrode (grafitne ili srebrne). Membrana selektivna za kalijeve ione pripravljena je miješanjem valinomicina (koji služi kao ionofor), polivinil klorida i dioktil sebacata (u funkciji plastifikatora). Kao vodljivi sloj služila je smjesa grafita i PVB-a različitih masenih udjela, od 50 do 65 % grafita. Ispitivanja su provođena u otopinama kalijeva klorida raspona koncentracija od 10–1 do 10–6 mol/dm^3. Kao referentna elektroda korištena je Ag|AgCl|3M KCl||2M NaNO3 elektroda. Kao radne elektrode ispitane su klasična ionsko-selektivna (ISE) te grafitna i srebrna elektroda oslojene pretvorničkim grafit:PVB slojem te membranom selektivnom za K+ ione. Ispitivanja grafitnog:PVB sloja i K+–ISE provodila su se potenciometrijom, cikličkom voltametrijom i elektrokemijskom impedancijskom spektroskopijom. Najbolja je svojstva pokazala srebrna elektroda sa 65 %-tnom formulacijom grafita i PVB-a.
Abstract (english)
This thesis covers the preparation, application and testing of a membrane selective for potassium ions. A graphite:polyvinyl butyral layer with different graphite mass fractions was used as an intermediate layer between the membrane and the electrode (graphite or silver). The potassium–selective membrane was prepared by mixing valinomycin (ionophore), polyvinyl chloride and dioctyl sebacate (plasticizer). A graphite:PVB layer with different graphite mass fractions (w = 50, 55, 60 and 65 %) was tested as a conducting layer. Ag|AgCl|3M KCl||2M NaNO3 was used as reference electrode, while graphite and silver electrodes were used as working electrode. The experiment was carried out in solutions of potassium chloride (concentration range: 10–1–10–6 mol/dm^3). All experiments were conducted using potentiometry, cyclic voltammetry and electrochemical impedance spectroscopy. The silver electrode with a 65 % graphite formulation obtained the best properties.
