“…The amount of derivative produced is related to the concentration of catalyst. Cuprous ion has been determined by its catalysis of conversion of an aromatic diazonium salt (prepared from p-toluidine) to a chlorinated derivative, p-chlorotoluene (80). At 21 °C the limit of detection (concentration of sample that gives a signal of twice the standard deviation of the blank) is reported as 0.25 ppm of Cu(I).…”

“…The presence of Fe(II), on the other hand, was found also to increase the production of p-chlorotoluene, the chromatographically measured species. The authors have also determined Fe(III) by a similar procedure (80). In this case Fe(III) catalyzes the reaction between anisole and H202 (in presence of hydroquinone) producing o-methoxyphenol which is chromatographically determined.…”

KINETIC ASPECTS OF ANALYTICAL CHEMISTRYHoraclo A. Mottola was born in Buenos Aires, Argentina, and received undergraduate and graduate education at the University of Buenos Aires. He earned Licentiate and Doctoral degrees from the University of Buenos Aires and did predoctoral work with Professor Ernest B. Sandell at the University of Minnesota (Minneapolis). He spent two years at the University of Arizona (Tucson) as a postdoctoral research fellow In Professor Henry Freiser's research group. After teaching for two years at the University ot the Pacific (Stockton, CA), he joined OSU in the fall of 1967. Dr. Mottola's research interests include studies on the role of kinetics in analytical chemistry (including reaction reate determinations), analytical separations (solvent extraction and liquid-liquid chromatography), continuousflow analysis, and analytical application of photochromism.

“…Excess levels of free iron, however, are considered to be cytotoxic and can cause severe neurological disorders, such as Parkinson's disease, Friedrich's ataxia, Alzheimer's disease and Pica [3][4][5][6]. Many excellent reagents and techniques have been developed for the detection of Fe 3+ and Fe 2+ [7][8][9][10][11]. Most of them, however, are only effective at neutral pH.…”
