Abstract
Kafein je alkaloid odnosno purinski derivat iz skupine ksantina te može utjecati na budnost, pažnju, fizičku sposobnost, umor, razdražljivost, nervozu, glavobolju i slično. Budući da je elektroaktivna tvar, prisustvo kafeina se može odrediti primjenom voltametrijskih tehnika. Voltametrijske tehnike su elektrokemijske metode kod kojih je odziv na signal pobude struja, a odvijaju se u najčešće tro-elektrodnoj staklenoj ćeliji u kojoj se nalazi elektrolit u kojeg su uronjene radna, referenta i pomoćna elektroda. Zadatak ovog završnog rada je opisati najčešće primjenjivane voltametrijske tehnike za analizu kafeina u realnim uzorcima (hrana, dodaci prehrani), korištene elektrode, elektrolit i specifičnosti tehnike.
Abstract (english)
Caffeine is an alkaloid or purine derivative from the xanthine group and can affect alertness, attention, physical ability, fatigue, irritability, nervousness, headache, and so on. Since it is an electroactive substance, the presence of caffeine can be determined using voltammetric techniques. Voltammetric techniques are electrochemical methods in which the response to the excitation signal is a current, and they take place in the most common three-electrode glass cell In glass cell is an electrolyte in which the working, reference and auxiliary electrodes are immersed. The task of this final paper is to describe the most frequently applied voltammetric techniques for the analysis of caffeine in real samples (food, dietary supplements), the used electrodes, the electrolyte and the specifics of the technique.
