"Spectrophotometric Determination Of Total Cyanide, Iron - Cyanide Complexes, Free Cyanide And Thiocyanate In Water By A Continuous-flow System"
Analyst 1989 Volume 114, Issue 8 Pages 959-963
ohannes C. L. Meeussen, Erwin J. M. Temminghoff, Meindert G. Keizer and Ivo Novozamsky

Abstract: The spectrophotometric method used is based on that of Nagashima (Anal. Abstr., 1979, 36, 1B81), except that 1,3-dimethylbarbituric acid is used instead of barbituric acid, and 0.1 M phthalate instead of 1 M phosphate buffer. Total cyanide plus SCN- is determined spectrophotometrically after UV irradiation and distillation with citric acid at pH 3.8; free CN- plus SCN- is determined without irradiation and distillation; and SCN- is determined after masking of CN- with formaldehyde. Iron - CN- complexes are determined as the difference between the first two measurements. The detection limit is 0.6 µg L-1 of CN-, and recovery of Fe - CN- complexes is quantitative. Interference from NO3- is minimized.

"Improved Response Of Carbon-paste Electrodes For Electrochemical Detection In Flow Systems By Pretreatment With Surfactants"
Anal. Chem. 1987 Volume 59, Issue 7 Pages 958-962
F. N. Albahadily and Horacio A. Mottola

Abstract: Six different paste compositions (three commercial) were treated with aqueous 0.1% solution of Brij-35, Triton X-100 and Na dodecylbenzenesulfonate. The responses were evaluated by cyclic voltammetry with Fe(CN)64-, tris-(1,10-phenanthroline)iron(II), SO32- and NADH. An improved response was generally obtained from all the treated electrodes with greatly enhanced sensitivity in continuous-flow detection. The treatment lowered the uncompensated cell resistance of the pastes by removing or decreasing the insulating effect of the oily layer formed on smoothing the electrode surface.

"Dynamic Response Characteristics Of An Impinging-jet Amperometric Detector"
Electroanalysis 1990 Volume 2, Issue 6 Pages 463-469
Francis E. Powell, Arnold G. Fogg*

Abstract: By use of [Fe(CN)6]4- as test species an investigation was carried out to determine the dynamic response characteristics of the impinging-jet electrode described previously [cf Fogg and Summan, Analyst (London), 1984, 109, 1029]. Laminar flow from a straight delivery tube was modified by mixing stages in the electrode channel and its connections. The effective detection volume was ~7 µL and therefore the detector would not be expected to contribute significantly to overall dispersion in practical flow injection systems.
