摘要：

Direct potentiometry and potentiometric titration methods using potassium ferrocyanide solutions at pH 2.5 - 3 can be used to determine Fe(III) and Cu(II) ions in hydrochloric acid solutions. Ion-selective solid electrodes of the oxide vanadium bronzes (OVB) Na1.4Me0.6V12O30 (Me = Cu, Fe) are used for indication of the equivalence point.
