Abstract
U ovom radu ispitivan je odziv ion-selektivnih membrana na ione Fe 2+ s različitim udjelima nanočestica aluminijevog oksida pri pH=4 i pH=5. Membrane su bile sljedećeg sastava:  RF1 → FeS:Ag 2 S:PTFE = 1:1:2  AF1 → FeS:Ag 2 S:PTFE = 1:1:2 uz dodatak 1% čestica Al 2 O 3  AF2 → FeS:Ag 2 S:PTFE = 1:1:2 uz dodatak 0,5% čestica Al 2 O 3  AF3 → FeS:Ag 2 S:PTFE = 1:1:2 uz dodatak 0,25% čestica Al 2 O 3 Ispitivanja su provedena metodom slijednog razrjeđivanja dok se potencijali ne bi ustalili ili dok razlike nisu bile manje od 1mV. Za svaku membranu mjerenje je ponavljano 3 puta te su rezultati prikazani grafički. Ovakav postupak ispitivanje odziva membrana je brz, jednostavan i jeftin te je vrlo često korištena metoda prilikom potenciometrijskih mjerenja.
Abstract (english)
In this work, we examined the response of ion-selective membranes to Fe 2+ ions with different proportions of aluminum oxide nanoparticles at pH=4 and pH=5. The membranes had the following composition: • RF1 → FeS:Ag 2 S:PTFE = 1:1:2 • AF1 → FeS:Ag 2 S:PTFE = 1:1:2 with the addition of 1% Al 2 O 3 particles • AF2 → FeS:Ag 2 S:PTFE = 1:1:2 with the addition of 0.5% Al 2 O 3 particles • AF3 → FeS:Ag 2 S:PTFE = 1:1:2 with the addition of 0.25% Al 2 O 3 particles Tests were performed using the sequential dilution method until the potentials were stabilized or until the differences were less than 1mV. For each membrane, the measurement was repeated 3 times, and we presented the results graphically. This procedure of membrane response testing is fast, simple and inexpensive, and is a very often used method for potentiometric measurements.
