Abstract
The adsorptive modifying of silica by chitosan is carried out. The isotherm
of adsorption and the value of the limiting adsorption of chitosan on the
surface of fumed silica are found. The desorption of chitosan from the
surface of fumed silica has been investigated. The optimum conditions for
obtaining a chitosan-silica nanosorbent are determined. The scheme of
thermal decomposition of chitosan and chitosan adsorbed on the silica
surface is offered. It has been shown that, in the thermolysis of chitosan
adsorbed by the silica surface, the low-temperature maximum appears on
thermodesorption curves which corresponds to the thermolysis of segments
directly connected with the silica surface.
