ΜΕΛΕΤΗ ΚΑΤΑΛΥΤΙΚΟΥ ΠΡΟΣΔΙΟΡΙΣΜΟΥ ΙΧΝΟΣΥΓΚΕΝΤΡΩΣΕΩΝ ΙΟΝΤΩΝ ΣΙΔΗΡΟΥ (ΙΙΙ) ΚΑΙ ΒΑΝΑΔΙΟΥ (V)

A KINEMATIC METHOD IS DESCRIBED FOR THE DETERMINATION OF TRACE AMOUNTS OF IRON (III) AND VANADIUM (V). THE METHOD IS BASED ON THE CATALYTIC EFFECT OF IRON (III) AND VANADIUM (V) ON THE OXIDATION OF 3,5-DIAMINOBENZOIC ACID DIHYDROCHLORIDE BY HYDROGEN PEROXIDE AND POTASSIUM BROMATE, RESPECTIVELY. THE OPTIMAL CONDITIONS FOR BOTH ELEMENTS DETERMINED WERE FOUND BY STUDYING THE RATE DEPENDENCE OF THE CATALYSED AND THE NON-CATALYSED REACTION ON PH, TEMPERATURE, IONIC STRENGTHAND CONCENTRATIONS OF THE REACTANTS. THE PROPOSED METHODS WERE APPLIED SUCCESSFULLY TO THE ANALYSIS OF REAL SAMPLES. IRON WAS DETERMINED IN TOP WATER, IN GREEK WINES OF VARIOUS TYPES AND IN A STANDARD REFERENCE BIOLOGICAL MATERIAL (NBS), WHILST VANADIUM WAS DETERMINED IN TOP WATER AND IN STEEL SAMPLES.
