Abstract
U ovom radu koribten je novorazvijeni all-solid-state senzor sa vrstom membranom za određivanje anionskih tenzida u komercijalnim sustavima. Membrana norazvijenog senzora se sastoji od ionskog para DDA-TPB (dimetildioktadecilamonijev tetrafenil borat) koji je koribten kao senzorski materijal, te grafita i o-NPOE-a (2-nitrofenil oktil eter) kao plastifikatora. Metoda koribtena u istra~ivanju je potenciometrijska titracija. Ispitana su etiri razli ita titranta (cetilpiridinijev klorid, heksadeciltrimetilamonijev bromid, diizobutil-fenoksietoksi etil-dimetil benzil amonijev klorid i 1,3-didecil-2-metilimidazolijev klorid) koncentracije 4 × 10⁻³ mol L-1, pri emu je kao analit koribtena otopina natrijeva dodecil sulfata. Kao najpogodniji titrant izabran je cetilpiridinijev klorid zbog najve e to nosti i najve eg skoka potencijala u ekvivalentnoj to ki. Primjena novog all-solid-state potenciometrijskog senzora ispitana je određivanjem sadr~aja anionskih tenzida u tri komercijalna proizvoda, a metodom standardnog dodatka ispitana je to nost senzora. Rezultati su pokazali zadovoljavaju u preciznost i to nost prilikom određivanja sadr~aja anionskih tenzida u komercijalnim uzorcima pomo u novog all-solid-state potenciometrijskog senzora kao detektora zavrbne to ke titracije.
Abstract (english)
In this work, a newly developed all-solid-state sensor with a solid membrane was used for the determination of anionic surfactants in commercial systems. The membrane of the newly developed sensor consists of the ion pair DDA-TPB (dimethyldioctadecylammoniumtetraphenylborate), which was used as the sensor material, graphite and o-NPOE (2-nitrophenyl octyl ether) as plasticizer. The method used in the research is potentiometric titration. Four different titrants (cetylpyridinium chloride, hexadecyltrimethylammonium bromide, diisobutylphenoxyethoxy ethyl-dimethyl benzyl ammonium chloride and 1,3-didecyl-2-methylimidazolium chloride) with a concentration of 4 × 10⁻³ mol L-1 were tested, while the analyte was sodium dodecyl sulfate solution. Cetylpyridinium chloride was chosen as the most suitable titrant due to the highest accuracy and the highest potential jump at the equivalent point. The application of the new all-solid-state potentiometric sensor was tested by determining the content of anionic surfactants in three commercial products, and the accuracy of the sensor was tested using the standard addition method. The results showed satisfactory precision and accuracy when determining the content of anionic surfactants in commercial samples using a new all-solid-state potentiometric sensor as a titration endpoint detector.
