Effect of the Hydrodynamic Conditions for Sodium Alginate–Papain Colloidal System Synthesis on the Sorption Properties of the Biocomposite
The regularities have been studied for the formation of molecular associates upon the introduction of papain into a sodium alginate colloidal solution in the laminar low-speed, transient, and turbulent stirring regimes. The relationship between variations in the sorption capacity of the biopolymer composition and the kinetic regularities of the interphase transfer has been studied during the sorption binding of albumin, which is one of the protein-based components of wound exudates, with such components being subject to ensimatic cleavage. The state of the dispersed phase of the colloidal solutions has been estimated by the dynamic light scattering method. The properties of the formed biopolymer films have been studied using the methods of scanning electron microscopy, low-temperature nitrogen adsorption, and static albumin sorption from solutions of limited volumes. The data of the sorption experiments have been analyzed using the Boyd, Morris–Weber, and gel diffusion models, as well as the Lagergren pseudo-first-order and Ho–McKay pseudo-second-order kinetic models. The data have been obtained for substantiating the dosages of the biopolymer matrix used on wound-healing bandages and for the efficient binding of wound necrotic contamination during the time preset according to the technical requirements.
期刊介绍:
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
