Morphological and Chemical Analysis of Impurities in Ice Using the Environmental Scanning Electron Microscopy and Fluorescence Spectroscopy

Popis výsledku v původním jazyce

Accumulated and concentrated impurities can be stored in natural ice or snow. They are found to be rejected from the freezing solution to the ice grain boundaries, free ice surfaces or liquid/brine inclusions. Information about compartmentation and phasespeciation in ice is thus essential for the assessment of their fate. The location of impurities and their interactions with the water molecules of ice, still not sufficiently clarified, must be studied at low temperatures because thawing smears the information out. When the impurities keep their location while the surrounding ice sublimes, a 3D morphology of the ice boundaries is revealed. Environmental scanning electron microscopy (ESEM) is one of the few methods allowing direct observation of ice bulk sample with location and compartmentation impurities in dynamically changing conditions of relatively high pressure of gas and stable temperature of cooled sample holder.
