Abstract
U diplomskom radu ispitivao se odziv potenciometrijskih senzora s dodatkom nanočestica magnetita i hematita za određivanje željezovih(III) kationa pri pH = 1,00 i pH = 5,00 koristeći ionsko-selektivne membrane. Željeni odziv potenciometrijskog senzora treba pratiti nagib pravca prema zahtjevima Nernstove jednadžbe za trovalentne katione. Membrane su ispitivane na odziv prema željezovim(III) kationima u elektrokemijskoj ćeliji koristeći otopinu željezovog(III) sulfata i željezovog(III) nitrata kao izvora Fe 3+ s dodatkom kalijevog nitrata. Ispitivanja su provedena metodom slijednog razrjeđivanja. Iz dobivenih rezultata membrana PNF 1 eksperimentalno pokazuje dobar nagib kako u laboratorijski pripravljenoj otopini željezovog(III) nitrata tako i u standardnoj otopini Fe 3+ kationa. PNF 1 senzor stoga je dobar za kvalitativnu analizu, a za kvantitativnu analizu potrebno je provesti dodatne analize. Ostali senzori nisu pokazali zadovoljavajuće karakteristike u svrhu određivanja željeza.
Abstract (english)
In the thesis was examined response of potentiometric sensors with the addition of magnetite and hematite nanoparticles for the determination of iron(III) cations at pH = 1.00 and pH = 5.00 using ion-selective membranes. The desired response of the potentiometric sensor should follow the slope of the direction according to the requirements of the Nernst equation for trivalent cations. Membranes were tested for response to iron(III) cations in an electrochemical cell using a solution of iron(III) sulfate and iron(III) nitrate as a source of Fe 3+ with the addition of potassium nitrate. The tests were performed by the sequential dilution method. From the obtained results, PNF1 membranes experimentally show a good slope both in the laboratory-prepared solution of iron(III) nitrate and in the standard solution of Fe 3+ cation. The PNF1 sensor is therefore good for qualitative analysis, and additional analyzes are needed for quantitative analysis. Other sensors did not show satisfactory characteristics for the purpose of determining iron.
