Preparation of Submicron Chitosan-Alginate Particles and Study of Their Selective Sorption Properties with Respect to Amphiphilic Organic Compounds

Resumo

The effect of the composition of mixed dilute solutions of chitosan and sodium alginate on the size, ζ-potential, and weight yield of the submicron particles of the insoluble interpolymer polyelectrolyte complex, formed in these solutions, was examined. By the example of ionic dyes used as model sorbates it was shown that the composition of the initial solutions is a major factor in tuning the sorption properties of chitosanalginate carriers with respect to charged organic compounds.
