Abstract
A powdered halloysite/iron oxide composite has been synthesized by the chemical coprecipitation method. The sorption properties of halloysite and the composite have been studied with respect to tetracycline. The halloysite/iron oxide composite has been found to be a more efficient sorbent than halloysite. Mathematical processing of the experimental data has led to a conclusion that the kinetics of the sorption process can be described by the pseudo-first- or pseudo-second-order kinetic models. The antimicrobial properties of the synthesized composite samples with respect to E. coli M-17 bacteria have been studied before and after tetracycline adsorption. It has been revealed that the saturation of the composite with the antibiotic leads to a decrease in the viability of bacteria.
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.
