The purpose of the study was to develop an electrochemical method for detection of lead at low level of contamination in water samples using a carbon glassy electrode modified with the functionalized azulene: (2E)-2-(azulen-1-ylmethylidene) hydrazine carbothioamide (L) as a complexing polymer film. The modified electrodes were prepared in L solutions (1mM) in acetonitrile (CH3CN) containing tetra n-butyl ammonium perchlorate (0.1 M TBAP) as supporting electrolyte. The analyses were performed on Autolab PGSTAT 12 P...

The electrical power industry of the Russian Federation based on the performance of thermal power stations (TPS) is the largest consumer of the Russian coals. Currently the long-term development program of the Russian coal industry for the period till 2030 is adopted. One of its purposes is increasing supply of the Russian coal for power industry in the domestic market. The researchers dealing with the issues of power industry emphasize the drawbacks of the coal industry having negative influence on optimization o...

The aim of this study was to investigate the process of accumulation of some toxic metals in Salvia Officinalis cultivated in-situ and also in controlled laboratory experiment. In situ experiment was located in a highly polluted area, situated in the proximity of abandoned gold mine and a waste dump. In the study were collected and analyzed four different samples of Salvia Officinalis, grown on polluted soil situated in different geographic directions around a waste dump. The analytical investigation indicated tha...
