Abstract
FLUORĪDJONI, NOTEIKŠNAS METODES. Darbā tika aplūkota fluorīdjonu kvantitatīvā noteikšana ar dažādām instrumentālajām metodēm. Tika salīdzināta fluorīdjonu jonselektīvā elektroda metode ar spektrofotometriskajām metodēm: SPADNS un lantāna – alizarīnkompleksonu. Noteiktas fluorīdjonu masas koncentrācijas dažādos dzeramā ūdens paraugos, skaitļota rezultātu atgūstamība spektrofotometriskajām metodēm.
FLUORIDE IONS, DETERMINATION METHODS. In the work quantitative determination of fluoride ions with different instrumental methods is viewed. SPADNS, lanthanum – alizarincomplexone photometric and fluoride ion selective electrode methods are used. The contents of fluoride ions in different drinking water samples are determinated. The recoveries of fluoride ions of known addition in water samples for photometric methods are calculated.
