Abstract
U ovom radu ispitivane su odzivne karakteristike fluorid ionsko-selektivne elektrode (FISE) s membranom LaF 3 (Eu 1%) 8x5mm te unutarnjim elektrolitnim odnosno s unutarnjim čvrstim kontaktom pri pH 4,7. Ispitivan je i utjecaj nanočestica, koje su bile nanesene na površinu membrane, na odzivne karakteristike FISE. Elektroda uglavnom slijedi linearnu promjenu potencijala do koncentracije fluorida niže od 1×10 -5 mol L - 1 s promjenom potencijala po koncentracijskoj od 10 -5 do 10 -1 . Također je ispitan je i odziv elektrode u ovisnosti o vremenu. Stabilan potencijal za membranu LaF 3 (Eu 1%) 8x5mm se uspostavlja u vremenu od 0 min do 5 min, što ovisi o kondicioniranju same elektrode, ali i o unutarnjem kontaktu. Najbržu uspostavu stabilnog potencijala elektroda je pokazala s elektrolitnim kontaktom pri koncentraciji fluorida od 10 -3 mol L -1 .
Abstract (english)
In this paper, were examined the response characteristics of a fluoride ion-selective electrode (FISE) with a LaF 3 membrane (Eu 1%) 8x5mm and internal electrolyte and internal solid contact at pH 4.7.The effect of nanoparticles deposited on the membrane surface on the response characteristics of FISE was also examined. The electrode generally follows a linear change in potential up to a fluoride concentration lower than 1 × 10 -5 mol L -1 with a change in potential at a concentration of 10 -5 do 10 -1 The response of the electrode as a function of time was also examined. The stable membrane potential of LaF 3 (Eu 1%) 8x5mm is established in the time from 0 min to 5 min, which depends on the conditioning of the electrode itself and also on the internal contact. The fastest establishment of the stable potential of the electrode was demonstrated by electrolyte contact at a fluoride concentration of 10 -3 mol L -1 .
