Comparison of the Electrochemical and Enzymic Oxidation of 1,3,7-Trimethyluric Acid at Solid Electrodes

The influence of ultrasound on voltammetric measurements at a mechanically stable renewed mercury electrode was described. The measurements were carried out in a solution of 4,4'-bipyridyl in 0.1 M KCl + 0.01 M NaOH, in 1 . 10-4 M CdSO4 + 5 . 10-6 M tribenzylamine in 0.1 M H2SO4 and in 3 . 10-3 M CdSO4 + 1 . 10-4 M tribenzylamine hydrochloride. Possible development and applications of related electroanalytical techniques by using mercury and solid electrodes were discussed. A pronounced influence of ultrasound was observed mainly in cases where the kinetics and irreversibility of the electrochemical and related processes played an important role.

Metalloporphyrins (MP) and metallophtalocyanines (MPc) are innovative materials with catalytic properties that have attracted attention for their application for diverse electrochemical purposes. The presence of metallic centers in their structure offers a redox-active behavior that is being applied in the design of solid electrodes for the quantification of biomolecules, water contaminants, and pharmaceuticals, among others. Herein, we collect the recent information about porphyrin and phthalocyanine complexes as modifiers of electrodes, and the important aspects of the design, characterization, and application of these electrodes.
