"Flow Injection Single-point Titration Of Acids With Biamperometric Detection At Polarized Platinum Electrodes"
Anal. Chim. Acta 1987 Volume 194, Issue 1 Pages 269-274
Wojciech Matuszewski, Adam Hulanicki and Marek Trojanowicz

Abstract: Samples of acids (15 µL) were injected into a stream of water which was merged with a stream of 2 M NaI and 50 mM NaIO3 (2.4 mL min-1). The detector placed 10 cm from the merging point was a flow cell containing two 8-mm x 0.3-mm diameter platinum electrodes at a constant polarizing voltage of 100 mV. Rectilinear graphs of concentration. vs. current were obtained for 1 to 10 mM acid and, with online microcomputer data processing, a coefficient of variation <0.2% was achieved.

"Application Of The Flow Injection Analysis Method For Single-point Titration Of Acids"
Pr. Nauk. Inst. Chem. Nieorg. Metal Pierwiastkow R 1988 Volume 58, Issue 1 Pages 254-258
Matuszewski, W.

Abstract: Flow-injection single-point titration of acids is based on biamperometric measurement of iodine formed quant. in the reaction of iodide with iodate. Results are presented for determination of sulfuric, hydrofluoric, monochloroacetic, formic, and acetic acids. The slopes of the calibration plots, which are linear for about 1-10 mM acid, depend on the strength of the acid, decreasing from sulfuric acid to acetic acid. With microcomputer online data processing relative standard deviations were about 0.2%. (SFS)
