Determination of Mercury in Urine in Toxicological Laboratory
Dlasková, Z. ; Navrátil, Tomáš ; Kopanica, M. ; Pelclová, D.
Contamination of human body with mercury is very low. The normal level is about 20 ćg per 1 liter of urine. The traditionally applied method for determination of mercury in urine, spectroscopy, could be replaced after proper sample preparation

Dlasková, Z. ; Navrátil, Tomáš
The most frequently applied analytical methods and techniques in toxicological laboratories are described. The article shows review on sampling methods and sample preparations of body fluids for toxicological analytical purposes.
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.
