Polarography metal complexes

Brugmann [784] discussed different approaches to trace metal speciation (bioassays, computer modelling, analytical methods). The electrochemical techniques include conventional polarography, ASV, and potentiometry. ASV diagnosis of seawater was useful for investigating the properties of metal complexes in seawater. Differences in the lead and copper values yielded for Baltic seawater by methods based on differential pulse ASV or AAS are discussed with respect to speciation. [Pg.269]

Anodic stripping voltammetry (ASV) can be very usefiil in studies of metal complexation in natural aquatic systems. The technique can be used, under favorable conditions, to determine metal concentrations as low as 10 molL. Further, and again under appropriate conditions, stabihty constants may be determined in a manner analogous to that used in polarography. The principle of the technique involves deposition of a metal ion in reduced form on a static mercury electrode followed by reoxidation through reversal of the polarity. The reoxidation current is related to the metal concentration in the analyte. In the presence of a... [Pg.4548]

Polarography created by Heyrovsky in 1929 was introduced to Japan by Masuzo Shikata, a coworker of Heyrovsky, and this technique quickly attracted interest of analytical chemists and electrochemists in Japan. N. Tanaka and his coworker R. Tamamushi made a remarkable achievement in the field of oxidation-reduction reactions of metal complexes in solution by polarography. [Pg.4]

Normal-pulse polarography may be applied to solid-electrode voltammetry, which often is beset by electrode fouling (there is no periodic renewal of the electrode surface, as there is at the dme). This can be demonstrated for the electrolytic deposition of Ag and Au at solid electrodes and for the study of redox mechanisms of metal complexes ... [Pg.163]

Henry s research interests encompassed mass spectroscopy, proton magnetic resonance, and polarography of coordination compounds especially metal complexes of chelates such as p-diketonates. He was the coauthor of three popular freshman chemistry textbooks, some of which went through as many as 10 editions College Chemistry With Qualitative Analysis (1963), General Chemistry (1972), and Basic Laboratory Studies in College Chemistry with Semi-Micro Quantitative Analysis (1986). [Pg.318]

All these studies gave the impetos for thorough and systematic studies of catalytic and adsorption effects in polarography of metal complexes. [Pg.152]
