| Popis: | This Bachelor Thesis is dedicated to the study of the electrochemically active substance 8-hydroxy-5-nitroquinoline. The stability of the prepared standard solution was monitored by UV/VIS spectrometry throughout the electrochemical measurements. A polished silver solid amalgam electrode was chosen as the working electrode. First, the optimum conditions for the measurements were determined by DC voltammetry and differential pulse voltammetry. The calibration dependence was subsequentlymeasuredbybothtechniquesintheconcentrationrangefrom1·10−7 to 1·10−5 mol/L. The DC voltammetry method was also used to measure the calibration dependence in model matrices of drinking and well water in the concetration order of 10−6 mol/L. To further investigate the electrochemical processes and controlling processes in the electrochemical transformation of 8-hydroxy-5-nitroquinoline, the cyclic voltammetry technique was used and applied at different polarization rates. |
