摘要：
The results of studying the sorption of copper(II) ions by composite sorbents based on chitosan and mineral reinforcing fillers from aqueous solutions of electrolytes and solutions containing dodecyldimethylamine-N-oxide are presented. It is shown that the composite sorbents "chitosan-glauconite" and "chitosan-zeolite" are characterized by a larger increase in the sorption capacity for Cu(II) ions in solutions containing surfactants than the composites "chitosan-silicon dioxide" and "chitosan-montmorillonite." The adsorption characteristics of the composite sorbents were compared with those of the initial hydrogel chitosan sorbent. IR spectra, diffraction patterns, and micrographs of the surface of the samples were obtained.
