Аннотация
It was spectrophotometrically determined that dilute aqueous mixtures of methylene blue cationic dye with sodium alginate are stable self-assembling systems from dissolved state noncovalent complexes. The influence of the mixture components, the molecular weight of sodium alginate and composition of the environment on the binding ability of the polymer toward to dye were investigated. The critical pH values and also amounts of inorganic salts, an oppositely charged polyelectrolyte and an organic solvent, causing a complete inhibition of complex formation and the release of dye were determined.
