Abstract
U ovom radu je ispitan odziv ionsko-selektivne membrane na bazi željezovog(III) fosfata na željezove(III) katione pri pH = 1. Vršilo se testiranje membrane koja je napravljena od željezovog(III) fosfata, srebrovog sulfida, Ag 2 S te politetrafluoretilena (PTFE) koji služi kao neaktivni nosač. Očitanjem potencijala je napravljen grafički prikaz ovisnosti elektrodnog potencijala membrane o aktivitetu željezovih(III) kationa. Usporedbom eksperimentalnih podataka i izračunatih vrijednosti može se utvrditi pokazuje li membrana odziv na željezove(III) katione. Pripravom otopina R 1 – R 5 (Fe 3+ - sulfosalicilna kiselina) te očitanjem apsorbancije na spektrofotometru napravljena je kalibracijska krivulja. Nakon mjerenja promjene apsorbancije s promjenom koncentracije željezovih(III) kationa, metoda UV-Vis apsorpcijske spektrofotometrije se može usporediti s potenciometrijskom metodom. Usporedba se radila tako da se ista koncentracija željezovih(III) kationa određivala i potenciometrijski i spektrofotometrijski. Značajke koje su uzete u obzir kod usporedbe metoda su jednadžbe pravaca te linearna dinamička područja.
Abstract (english)
In this thesis, was tested the response of ion-selective membrane based on iron(III) phosphate to iron(III) cations at pH=1. Tested membrane was made of iron (III) phosphate, silver sulfide, Ag 2 S and polytetrafluoroethylene (PTFE). Polytetraflouroethylene is used as an inactive carrier. Graphical representation of the electrode potential on the activity of iron(III) cations was made. By comparing experimental data and calculated values, it can be determined whether the membrane shows a response to iron(III) cations. A calibration curve was made by preparing solutions R 1 – R 5 (Fe 3+ - sulfosalicylic acid) and reading the absorbance on a spectrophotometer. After measuring the change in absorbance with the change in the concentration of iron(III) cations, the UV-Vis absorption spectrophotometry can be compared with the potentiometric method. The same concentration of iron(III) cations was determined both potentiometrically and spectrophotometrically and then a comparison was made. The compared features were te direction equation and linear dynamic range.
