- Аннотация: The adsorption of octa-4,5-carboxyphthalocyanine and its complexes with zinc, copper, cobalt(II), lead, and vanadyl from aqueous-organic solutions by a reversed-phase sorbent was studied under static conditions. Adsorption isotherms were constructed for the following solvents: dimethyl formamide-water (30 : 70) and dimethyl sulfoxide-water (30 : 70 and 50 : 50). The isotherms of adsorption of phthalocyanine and metal phthalocyanines were constructed. It was shown that the adsorption value is determined by the interaction of the solvent with the central metal ion. The values of the limiting monolayer adsorption, the Langmuir adsorption equilibrium constant, and the Gibbs free energy change were estimated.
