A method is proposed for the determination of copper and cadmium by atomic absorption spectrometry in a propane-butane-air flame with electrochemical and sorption preconcentration. Electrochemical preconcentration was ...

Procedures were developed for determining ionol by voltammetry and by coulometric titration with electrogenerated chlorine using the amperometric indication of the titration end point. Possible mechanisms of ionol oxidation ...

It was found that an iodine-modified platinum electrode gives a linear potentiometric response to 1.0 × 10-5 to 1.0 × 10 -3 M ascorbic acid in model solutions. Ascorbic acid in some preparations was determined by potentiometry. ...

A number of amino acids (glycine, alanine, serine, threonine, lysine, arginine, methionine, cysteine, cystine, asparagine, and glutamic acid) give a voltammetric response on platinum, gold, copper, and nickel electrodes ...
