The Application of the Elimination voltammetry in the Study of Phytochelatine Complexes with Zinc
 Šestáková, Ivana ; Navrátil, Tomáš ; Velek, Jiří
For two synthetically prepared phytochelatins – PC2 and PC3 - the formation of complexes with zinc ions was studied in borate buffer pH 8.5, using DC and DP voltammetry on HMDE. In both cases, in addition to complexation, oxidation of peptide takes place. Elimination voltammetry with linear scan could distinguish particular Zn-complexes and showed their reduction at adsorbed state and the influence of kinetics -slow formation or labile behaviour of complexes.

The Use of Amalgam Electrodes in Electrochemical Analysis of Azidothimidine in Remedy Form
 Pecková, K. ; Moreira, J. C. ; Josypčuk, Bohdan ; Navrátil, Tomáš ; Zima, J. ; Barek, J.
Azidothymidine (3´-azido-3´-deoxythimidine, AZT, Zidovudin) is a nucleoside analog, derived from thimidine. This compound prohibids the replicatrion of HIV virus. The article deals with its voltammetric determination using mercury and silver solid amalgam electrode. The results are compared with those obtained using HPLC.

Determination of thiodiglycolic acid concentration in case remethylation disorder
 Navrátil, Tomáš ; Šenholdová, Z. ; Heyrovský, Michael ; Přistoupilová, K. ; Přistoupil, T. I. ; Surovcová, H.
The new simple voltammetric method we described recently was useful in determining thiodiglycolic acid (TDGA) levels in urine samples. The article deals with revealing of time dependencies of the concentration levels of this metabolic product in healthy persons as well as persons suffering from various diseases. The corresponding metabolic processes are described.

Voltammetric Determination Phenylglyoxylic Acid in Urine Using Graphite Composite Electrode
 Navrátil, Tomáš ; Šenholdová, Z. ; Shanmugam, K. ; Barek, J. ; Surovcová, H.
Phenylglyoxylic acid is metabolized in human body from vinylbenzene (styrene) (from which polystyrene is produced). Presented work deals with determination of this metabolite in human urine using carbon composite electrode. In the article are compared the results of analysis of the certified material (urine), achieved on the mercury and on the carbon composite electrodes.
