Optimum working conditions for the flow injection analysis (FIA) measurements were examined. In addition, under optimum conditions, potentiometric performance characteristics of the Fe3+ ion-selective electrode were investigated. Electrode had a linear response in the concentration range of 1.0 x 10(-3)-1.0 x 10(-6) M (R-2=0.9961, y=24.7+772.0). Reproducibility of the electrode responses was very satisfied. The potential of Fe3+ ion selective electrode was decreased intra and inter day 0.9 % and 3.7% respectively. The designed flow-through cell system as Fe3+ detector revealed sampling rates of approximately 50 injections per hour. The obtained results in FIA were in a good agreement with AAs results at % 95 confidence level for each syrups.eninfo:eu-repo/semantics/closedAccessIron-selective electrodedeterminationflow injection systempotentiometersyrups analysisArticleQ3Q2112104108WOS:000350481300004
