Chromatographic
characteristics of silica modified with chitosan and it derivatives
Abstract
Number of new
sorbents based on silica modified with chitosan and it derivatives were
prepared and chromatographic characteristics of the sorbents were evaluated.
The effect of the nature of modifier on the retention of polar and non-polar
organic substances was studied. It was pointed out that sorbents obtained are strong-polar
stationary phases, thus, it can be used for the resolving of organic polar
substances at normal-phase chromatographic conditions. Enantioselective
properties of the sorbents were investigated.
