Sažetak:
Continuous-flow (CF) and flow-injection (FI) analysis using the fluoride ion-selective electrode (FISE) as detector have been investigated. The measurements were performed in a home-made cell under appropriate flow conditions (2.86 or 3.45 ml min-1, 0.2 ml samples, 10-6 M sodium fluoride). The calibration graph was obtained by plotting the signal height versus concentration of iron in the range of Fe(III) concentration from 10-5 to 10-1 M in acetate buffer (pH 2.8 or 3.4). In all described procedures, the range of linear response extends to the Fe(III) concentration from 1×10-3 to 1×10-1 M, with detection limit 9×10-5 M. The effect of double-line, two-line flow manifold and CF was investigated and discussed.
