Abstract
Površinski aktivne tvari, ili tenzidi, u okolišu završe: ispuštanjem u rijeke nakon procesa pročišćavanja otpadnih voda ili izravnim ispuštanjem kanalizacije gdje ne postoje uređaji za pročišćavanje otpadnih voda. Najveće količine tenzida nalaze se u otpadnim vodama tekstilne industrije, industrije deterdženata, kemijske industrije, industrije agrokemikalija, farmaceutske industrije, kozmetičke, industrije papira i iz domaćinstva. Za određivanje anionskih tenzida u otpadnim vodama korišten je potenciometrijski DMI-TPB tenzidni senzor. Karakteristike tenzidnog senzora određene su na modelnim uzorcima pomoću direktne potenciometrije i potenciometrijskim titracijama. U pet uzoraka otpadnih voda nisu detektirani anionski tenzidi iznad granice detekcije DMI-TPB tenzidnog senzora. Metodom standardnog dodatka anionskih tenzida, u dva koncentracijska područja, utvrđen je niski negativni utjecaj složenog matriksa realnih uzoraka otpadnih voda na mogućnost određivanja anionskih tenzida pomoću DMI-TPB tenzidnog senzora.
Abstract (english)
Surface active agents, or surfactants end up in the environment: through discharge waters from the wastewater treatment plants into or by the direct discharge of raw sewage where no wastewater treatment is available. The highest concentration of surfactants are released by a textile, detergent, chemical, agrochemical, pharmaceutical, cosmetic and the paper industry as well as households. In this paper, a potentiometric surfactant sensor was used to detect anionic surfactants in wastewaters. The surfactant sensor was characerised by direct potentiometry and potentiometric titration. In five samples of wastewaters no anionic surfactants were found above the detection limit of DMI-TPB surfactant sensor. A standard addition method was employed by adding anionic surfactants, at two concentration levels, to wastewater samples. There was no signifficant influence of the wastewater complex matrix on anionic surfactant detection by DMI-TPB surfactant sensor.
