Abstract

A fluorescent study of aquatic humic substances (AHS) in ice has been performed in order to make the first step toward elaboration of a remote technique for their diagnostics in aqueous solid-phase-containing systems. The fluorescence spectra of AHS in ice samples were obtained for different temperatures ranged from 0 to 150 degree(s)C. An unusual distortion of the fluorescence band shape has been observed at low temperatures. Some conclusions on the form of presence of AHS in ice were made on the base of the spectroscopic study. Several specific experiments were carried out to characterize the crystallization process in AHS aqueous solutions.
