Abstract
Ispitan je odziv ionsko–selektivnih membrana na željezove(III) ione pri pH = 1 i pH =1,5, te utjecaj udjela teflona, kao neaktivnog nosača, na odziv samih membrana. Svako mjerenje je ponovljeno minimalno tri puta. Ispitivanje odziva izvršeno je potenciometrijski zbog jednostavnosti i praktičnosti metode, ali i njene pristupačne cijene. Selektivnost metode povećana je promjenom reakcijskih uvjeta, odnosno promjenom pH otopine uzorka. Membrane su se ispitivale u elektrokemijskoj ćeliji koristeći otopinu željezovog(III) klorida, pripremljenu u puferu sumporne kiseline, metodom slijednog razrjeđivanja. Za svako mjerenje zabilježena je vrijednost elektrodnog potencijala. Razrjeđivanje je trajalo dok razlika između dvaju mjerenja nije iznosila 1-2 mV.
Abstract (english)
The main purpose of this thesis is testing the response of ion–selective membranes on iron (III) ions in pH = 1 and pH = 2, and Teflon part influence, as inactive carrier, on the composition of membranes. Each measurement was repeated minimum three times. The potentiometric method was used to test the response because of its simplicity and practicality, and also its affordable cost. The selectivity of the method is increased by changing the reaction conditions such as the pH of the sample solution. Membrane electrodes are tested for in electrochemical cell by using iron (III) chloride, prepared in sulfuric acid buffer, using sequentially dilution method. The value of the electrode potential was recorded for each measurement. Dilution was made until the potential difference between two measurements reached about 1-2 mV.
