Abstract
Tenzidi kao površinski aktivne tvari sadrže hidrofilnu glavu i hidrofoban rep te kao takvi smanjuju površinsku napetost. Ovisno o naboju glave, dijele se na anionske, kationske, amfoterne te neionske tenzide. Jedna od najčešće korištenih analitičkih metoda kojom se određuju tenzidi jest potenciometrijska titracija koja se temelji na mjerenju razlike potencijala između indikatorske i referentne elektrode. Cilj ovog rada bio je ispitati točnost određivanja anionskih tenzida s različitim brojem ugljikovih atoma u hidrofobnom dijelu molekule (C10, C12, C14), koristeći tenzidne senzore na bazi kvaternih amonijevih soli. Testirano je pet tenzidnih senzora: KA1-TPB, KA2-TPB, KA3-TPB, KA4-TPB te KA5-TPB pri čemu su svi pokazali zadovoljavajuću točnost što ukazuje na činjenicu da točnost određivanja anionskih tenzida ovim senzorima ne ovisi o vrsti anionskog tenzida.
Abstract (english)
Surfactants in their structure contain hydrophilic head and hydrophobic tale and they reduce surface tension. Depending on the charge of the head, surfactants are classified as anionic, cationic, amphoteric and nonionic surfactants. One of the most commonly used analytical methods for surfactants determination is potentiometric titration based on measuring the potential difference between the indicator and reference electrode. The aim of this paper was to examine the accuracy of the determination of anionic surfactants with different number of carbon atoms in the hydrophobic part of the molecule (C10, C12, C14), using surfactant sensors based on quaternary ammonium salts. Five surfactant sensors were tested: KA1-TPB, KA2-TPB, KA3-TPB, KA4-TPB and KA5-TPB. All of them showed satisfactory accuracy, which indicates the fact that the accuracy of anionic surfactants determination using these sensors does not depend on the type of anionic surfactant.
