<p>U okviru ove doktorske disertacije pažnja je sa jedne strane posvećena razradi NMR spektrometrijskih i veoma osetljivih hromatografskih (HPLC/DADi HPLC/TLS) metoda, a sa druge strane razradi jednostavnijih spektrofotometrijskih i voltametrijskih metoda za određivanje odabranih neonikotinoida. Kao posebno vredan doprinos, razrađena je metoda pripreme ekološki pogodne bizmut-film elektrode na staklastom ugljeniku i na planarnoj ugljeničnoj elektrodi. Efikasnost elektrode je upoređena sa elektrodom modifikovanom filmom od žive. Za ispitivanje površine radnih elektroda primenjena je i (SEM/EDS) metoda. Razrađene metode su testirane za određivanje neonikotinoida iz komercijalnih formulacija, kao i iz uzoraka krompira, kukuruza, paprike, meda i površinske vode.</p> / <p>The Ph. D. thesis is concerned with the development of NMR spectrometric and very sensitive chromatographic (HPLC/DAD and HPLC/TLS) methods, on the one hand, and simpler spectrophotometric and voltammetric methods on the other, for the determination of selected neonicotinoids. As an especially valuable contribution, a procedure has been developed for the preparation of an environment-friendly bismuth film electrode on glassycarbon and planar carbon electrode. The achieved efficiency of such electrode was compared with that of mercury film electrode. Surface morphology of the working electrodes was studied by the SEM/EDS method. The developed methods have been tested for the determination of the neonicotinoids from their commercial formulations, as well as from samples of potato, maize, pepper, honey, and surface water.</p>
