Abstract
U ovom radu formirane su dvije izvedbe čvrstofaznih referentnih elektroda (SSRE, solid-state reference electrode). Prva izvedba (RM1) temelji se na nanošenju zaštitne membrane od poli(vinil butirala) (PVB) na kemijski kloriranu srebrnu elektrodu. Za drugu izvedbu (RM2) formulirana je PVB-membrana zasićena srebrom, srebrovim kloridom te natrijevim kloridom. Membrane su prvo nanesene na disk elektrode: RM1 na srebrnu elektrodu te RM2 na elektrodu od staklastog ugljika (GC-elektroda). Po sušenju i kondicioniranju, provedeno je potenciometrijsko testiranje elektroda u nizu standardnih otopina širokog raspona koncentracija, uključujući: KCl, NaCl, CaCl2 te NaNO3. Ispitan je utjecaj pH na elektrodni odziv, za što je korišten citratni pufer širokog raspona pH vrijednosti od 2 do 12. Primjenjivost ovako pripremljenih elektroda ispitana je u postupku baždarenja komercijalne natrijeve ionsko-selektivne elektrode. Nakon što je potvrđena zahtijevana naponska stabilnost pripremljenih SSRE, proveden je transfer na inkjet ispisane Ag-elektrode na PET podlozi. RM1 i RM2 su nakapane na ispisane elektrode te su elektrokemijski ispitane jednako kao disk elektrode. Cilj je ispisivanje plošnih all-solid-state elektroda koje bi doprinijele optimizaciji i minijaturizaciji elektrokemijskih senzornih sustava.
Abstract (english)
In this work, two versions of solid-state reference electrodes (SSRE) were formed. For the first one, a protective poly(vinyl butyral) membrane (RM1) was drop-cast on a chemically chlorinated disc Ag-electrode. The second realization was made by drop-casting a PVB membrane saturated with silver, silver chloride and sodium chloride (RM2) on a disc glassy carbon electrode (GC-electrode). After drying and conditioning, potentiometric testing of the electrodes was performed in a number of standard solutions having a wide range of concentrations, including: KCl, NaCl, CaCl2 and NaNO3. The influence of pH on the electrode response was investigated, for which a citrate buffer with a wide pH range from 2 to 12 was used. After the required voltage stability of the prepared SSREs was confirmed, a transfer to inkjet printed Ag-electrodes on a PET substrate was performed. RM1 and RM2 were drop-cast on the printed electrodes. These were electrochemically tested in the same way as the disk electrodes. This work aimed to make sustainable all-solid-state horizontal electrodes that would optimize and miniaturize electronics and sensor units.
