Abstract
Tenzidi su sastavni dio mnogih proizvoda koji se koriste u industriji i u kućanstvu. Svakim danom se proizvode u sve većoj količini i mnogo ih završi u okolišu i tamo se nakuplja. Postoji velika potreba za brzim, jeftinim i jednostavnim načinom određivanja tenzida u proizvodima i u otpadnim vodama. U ovom radu je ispitana selektivnost pet tenzidnih senzora na bazi novih kvaternih amonijevih soli u otopinama devetnaest interferenata. Svi senzori su pokazali dobru selektivnost za anionski tenzid natrijev dodecilsulfat (NaDDS). Ispitan je i utjecaj pH u rasponu od 2 do 12 na odziv senzora, pri čemu je utvrđeno da promjena pH nema velik utjecaj. Dinamički odzivi senzora su također dobri. Uporabljivost senzora u realnim sustavima je ispitana u otopinama tri komercijalna deterdženta i rezultati su uspoređeni s rezultatima dobivenim titracijom u dvije faze.
Abstract (english)
Surfactants are constituents of many products that are used in industry and in the household. Every day they are produced in increasing quantities and many end up in the environment and accumulate there. There is great need for a fast, cheap and simple way to determine surfactants in products and in wastewater. In this paper, the selectivity of five surfactant sensors based on quaternary ammonium salts was examined in solutions of nineteen interferences. All sensors showed good selectivity for anionic surfactant sodium dodecyl sulfate (NaDDS). The effect of pH in the range of 2 to 12 on the sensor response was also examined and it was found that the change in pH does not have large effect. Dynamic responses of the sensors are also good. The applicability of the sensors in real systems was tested in solutions of three commercial detergents and results were compared with results obtained by two-phases titration.
