Voltammetric Determination of Genotoxic 4-Nitroindane at Mercury and Silver Amalgam Electrodes
 Burdová, Vendula ; Vyskočil, Vlastimil (advisor) ; Zima, Jiří (referee)
Presented Diploma Thesis is focused on electroanalytical determination of genotoxic 4-nitroindane, one of the nitrated polycyclic aromatic hydrocarbons (NPAHs). A hydrocarbon indane (a component of petrol) is a precursor of 4-nitroindane. NPAHs are produced all above by combustion processes in gasoline and diesel engines. It has been shown that NPAHs can be many times more mutagenic or carcinogenic than their parent PAHs, so the analysis of these dangerous pollutants becomes important for modern environmental analytical chemistry. Optimal conditions for determination of 4-nitroindane have been investigated in buffered water-methanolic solutions and electrochemical transformations of 4-nitroindane have been studied by DC voltammetry (DCV), differential pulse voltammetry (DPV) and cyclic voltammetry at a hanging mercury drop electrode (HMDE) and at a mercury meniscus modified silver solid amalgam electrode (m-AgSAE). For voltammetric determination of 4-nitroindane, the following techniques were used: DCV (limit of quantification (LQ) ~ 7. 10-8 mol. l-1 ), DPV (LQ ~ 1. 10-7 mol. l-1 ) and adsorptive stripping voltammetry (AdSV; LQ ~ 7. 10-9 mol. l-1 ) at HMDE, and DCV (LQ ~ 1. 10-7 mol. l-1 ) and DPV (LQ ~ 1. 10-7 mol l-1 ) at m-AgSAE. The applicability of the newly developed...
