Sažetak
Potentiometric ion determination method is very inexpensive, simple and reasonably fast method so due to that it is often applied for different cations or anions determination. “Home-made” ferrous ion-selective electrode has been prepared by constructing a solid membrane disk consisting of <45 µm sized particles of silver sulphide, ferrous sulphide and PTFE. Ratio of FeS:Ag2S:PTFE in membrane was 1:4:5. Prepared membrane was built in specially constructed electrode body made of Teflon. Membrane was tested to response of ferrous cations in acetic buffer (pH = 4.00). Testing were performed in laboratory prepared 0.1 mol L–1 iron(II) sulphate solution and results showed linear membrane response for ferrous cations in concentration range between 0.1 mol L– 1 and 1.95·10-4 mol L–1 with change of 32.3 mV per decade and detection limit of 1.45·10-4 mol L–1. Prepared membrane was also used for ferrous determination in real sample solution of dietary supplement which contains iron(II) sulphate as active substance in very good agreement with declared results.
