Sažetak
Design of the fluoride ion-selective electrode (FISE) as the tubular detector used in the flow injection analysis (FIA) has been described. Among other things, this design makes it possible to use various internal contacts. The effect of pH on peak height and detection limit in the pH range from 2.8 to 8.0 has been examined. The effect of flow rate and sample injection volume on peak height and range of linear response has also been examined. The flow rates rang from 0.56 mL/min to 4.05 mL/min, while the injection volumes are 100 and 200 mL. The optimum conditions are carrier solution (0.1 M KNO3, buffer pH 4 and 10-6 M NaF), flow rate 1.54 mL/min and sample injection volume 100 mL. Applicability of FISE as the tubular detector in determination of Fe(III)-ions and Al(III)-ions by flow injection analysis has been examined at pH values of 2.8; and 3.4.
