Abstract

N-nitrozamini dezinfekcijski su nusprodukti koji nastaju reakcijom oksidacije sekundarnih ili tercijarnih amina pomoću nitrozacijskog reagensa. Njihova opća formula je R1N(-R2)-N=O. Široko su rasprostranjeni u sustavima za opskrbu pitkom vodom i u vodama u okolišu. Istraživanja su pokazala da nitrozamini imaju štetne učinke na ljudsko zdravlje te je potrebno ograničiti njihove koncentracije u vodi. Za analizu N-nitrozamina koriste se kromatografske metode, uobičajeno su to plinska ili tekućinska kromatografija vezane sa spektrometrijom masa nakon odgovarajuće pripreme uzorka. U ovom radu opisane su analitičke metode određivanja N-nitrozamina u vodi za piće i otpadnim vodama.

Abstract (english)

N-nitrosamines are disinfection by-products that arise from the oxidation reaction of secondary or tertiary amines using a nitrosating agent. Their general formula is
R1N(-R2)-N=O. They are widely distributed in drinking water supply systems and in environmental waters. Studies have shown that nitrosamines have carcinogenic effects on human health, and it is necessary to limit their concentrations in water. Chromatographic methods are used for the analysis of N-nitrosamine, usually gas and liquid chromatography coupled to mass spectrometry. Sample preparation is required before analysis. Analytical methods for the determination of N-nitrosamine in drinking water and wastewater are described in this paper.
