Sažetak
There is increasing evidence for the importance of studies of the nature, properties and role of the sea-surface microlayers. Although the physical and chemical properties of sea-surface microlayers have been studied extensively, there is still a lack of knowledge about physico-chemical processes governing the formation and properties of the surface microlayers. Sea-surface microlayers can be studied either in an original sample without any pretreatment, or they can have been previously extracted by organic solvent and then investigated as ex-situ reconstructed film. Physico-chemical characteristics of natural and ex-situ reconstructed sea surface microlayer samples were studied using a complex methodological approach. Monolayer techniques, Brewster angle microscopy, reflection spectroscopy and electrochemical methods can be very efficient analytical tools for making a physico-chemical characterization of natural films. These techniques have been used to give better insight into the morphology of natural films, relations between concentration and type of substances and properties of films regarding exchange between film and subsurface.
