Sažetak
Electrocanalytical methods provide simple measurements procedure and prompt response for relatively low cost. Combined with the high sensitivity and selectivity, along with possibility to conduct in-situ measurements, electroanalytical methods are strong analytical tool for characterization and quantification of different sulphur species [1-7]. Recently it was shown that electroanalytical methods can differentiate between truly dissolved, and particulate sulphur fractions including sulphur based nanoparticles (NPs) in water environment [4, 5]. Features of electroanalytical methods, especially voltammetry, makes them appropriate for use as monitoring tools in assessment of water quality in natural environment with special emphasis for trace pollutant analyses (sulphur species [1-7], organic compounds [6-10], trace metals [1, 7, 11, 13], engineered and natural nanoparticles [4, 5, 14-16]. Voltammetry is the only technique that allows speciation and determination of the dissolved sulphur and trace metal species without many sample handling. Speciation of these compounds affects their biogeochemical cycling processes as well as biological impacts. Thus, electroanalytical measurements in natural waters are essential in order to obtain complete information on the speciation and to fully understand the geochemical cycling and bioavailability (toxicity) of the studied species.
