Abstract
Cilj rada je dobivanje slabo topljivog taloga LaF 3 taloženjem NaF s La(NO 3 ) 3 uz dodatak europija. Talog je dobiven taloženjem uz miješanje, bez miješanja te uz povremeno miješanje. Membrane su pripravljene miješanjem dobivenog taloga s europijem. Pripravljen membrane su se umetale u laboratorijski izrađeno tijelo za elektrodu. Odzivne karakteristike elektrode ispitivane su metodom slijednog razrjeđenja počevši od koncentracije fluorida 10 -1 do 10 -7 mol L -1 . Unutarnji elektrolitni kontakt postignut je korištenjem otopine KCl, c( KCl) = 3 mol L -1 . S ciljem postizanja boljih odzivnih karakteristike na površinu membrana nanosile su se nanočestice Fe X O Y . Pripravljene membrane pokazale su linearnu promjenu potencijala u koncentracijskom području od 10 -1 do 10 -2 mol L -1 s promjenom potencijala po koncentracijskoj dekadi od 10,00 do 24,29 mV. Najbolje odzivne karakteristike pokazala je nekondicionirana membrana dobivena prešanjem 0,45 g LaF 3 i 0,05 g teflona s 3% europija.
Abstract (english)
The aim of this diploma thesis is gaining low soluble precipitate of LaF 3 from NaF and La(NO 3 ) 3 with addition of Europium. Precipitate is obtained by percipitating with stirring, without stirring and periodically stirring. Membranes are prepared by mixing gained precipitate with Europium. The prepared membranes were inserted into a body made in laboratory for electrodes with purpose of measuring potential of the electrode. The response characteristic for the electrode were tested by sequential dilution starting with the fluoride concentration from 10 -1 to 10 -7 mol L -1 . Interior electrolyte contact was achieved using solution KCl, c(KCl) = 3 mol L -1 . To get better response characteristics Fe X O Y nanoparticles were to be applied to the surface of the membrane. Prepared membranes showed linear change of potential in concentration area of 10 -1 to 10 -2 mol L -1 along with potential change at concentration decade of 10,00 to 24,29 mV. Unconditioned membrane, made with pressing of 0,45 g LaF 3 and 0,05 g teflone with 3% Europium, showed the best responsive characteristics.
