"Amperometric Determination Of Hydrogen Peroxide In Pickling Baths For Copper And Copper Alloys By Flow Injection Analysis"
Anal. Chim. Acta 1983 Volume 145, Issue 1 Pages 189-196
Hans Lundbäck

Abstract: The hydrogen peroxide is oxidized at + 1.5 V vs. SCE at a glassy carbon electrode of the wall-jet type. The samples are diluted about 100 times in a dispersion coil before entering the amperometric detector. The calibration curve is linear from 10^-4 to 1 M H2O2, when 5 µL samples are used. With 50 µL samples the detection limit decreases to 10^-6 M H2O2. Neither metal ions (Cu2+, Zn2+, Ni2+, Al3+) up to 0.5 M nor changes in the sulfuric acid concentration of the samples between 0.1 and 1 M interfere with the hydrogen peroxide determination. About 75 samples can be analyzed per hour.

"Constant-potential Pulse Polarographic Detection In Flow Injection Analysis Without Deaeration Of Solvent Or Sample"
Anal. Chim. Acta 1986 Volume 179, Issue 1 Pages 381-388
Glen G. Neuburger and Dennis C. Johnson

Abstract: The use of constant-potential-pulse polarography enabled the detection of Pb(II) and Cd in solution (pH 7) to be carried out at a dropping-mercury electrode without de-aeration of sample or solvent. The supporting electrolyte was 0.1 M KNO3 - 0.01 M HNO3. The method was used in conventional polarographic cells or, for small samples, in flow injection systems; the determination of Cu(II) in electroplating solution is described.

"Ionometric Determination Of Tetrafluoroborate Ions In Electrolytes From Electroplating Productions By Flow Injection Analysis"
Zavod. Lab. 1992 Volume 58, Issue 12 Pages 15-16
Evsevleeva, L. G.; Petrukhin, O. M.; Urusov, Yu. I. (SFS)

Abstract: The title method is developed for the determination of tetrafluoroborate in Sn- and Cu-plating baths. Fluoride electrode immersed in phosphate buffer solution containing 0.1 M NaF is used as reference electrode. BF4-selective membrane electrode is used as indicator electrode. The sample solution should be diluted to 10^-1-10-3 mol analyte/L before determination The relative standard deviations are 0.009-0.017 and 0.011-0.016 for 420 and 600 measurements/h, respectively.
