Abstract

Napredni oksidacijski procesi pronalaze sve veću primjenu u obradi otpadnih voda. Iako omogućavaju uklanjanje velikog broja organskih onečišćivala koja nije moguće ukloniti konvencionalnim metodama obrade vode, ovi procesi mogu uzrokovati nastanak spojeva toksičnijih i za okoliš štetnijih od izvornog spoja. Iz tog razloga je potrebna potpuna strukturna analiza međuprodukata razgradnje različitih onečišćivala, a taj proces zahtjeva primjenu naprednih analitičkih metoda. Danas se u tu svrhu najčešće koriste spregnute tehnike kao što su plinska kromatografija-masena spektrometrija i tekućinska kromatografija-masena spektrometrija te hibridni spektrometri poput kvadrupol-brzinskog analizatora masa i kvadrupol-linearne ionske klopke. Kvalitativna analiza izvornih spojeva, ali i transformacijskih produkata pojedinih onečišćivala, ključna je za razumijevanje reakcijskih putova razgradnje onečišćivala naprednim oksidacijskim tehnikama te samim time i za procjenu učinkovitosti, praćenje i optimiranje takvih procesa te bi kao takva trebala biti sastavni dio njihova provođenja.

Abstract (english)

Advanced oxidation processes are finding increasing application in wastewater treatment. Although they allow the removal of a large number of organic pollutants that cannot be removed by conventional methods of water treatment, these processes can cause generation of compounds that are more toxic and environmentally harmful than the parent compound. For this reason, a complete structural analysis of the degradation products of different pollutants is required, and this process requires advanced analytical methods. Today, the most commonly used methods are coupled techniques such as gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry, as well as hybrid spectrometers such as a quadrupole-time-of-flight mass analyzer and quadrupole-linear ion trap. Qualitative analysis of the parent compounds, as well as the transformation products of individual pollutants, is crucial for understanding the reaction pathways of pollutants degradation by advanced oxidation processes, and thus for evaluating the efficiency, monitoring and optimization of such processes. As such, qualitative analysis should be an integral part of their implementation.
