Chrome–Polymer Composite as a Precursor for Obtaining a Sorbent with Selective Properties
A composite based on a cross-linked ionic polymer containing functional groups [–N(CH3)3]+ and a Cr3+ cation was obtained and studied. As a result of the contact of the polymer with the KCr(SO4)2 solution, the jarosite mineral-type composite is formed: R4N[Cr3(OH)6(SO4)2], in which R4N+ is the polymer group. Considering that the composite can be used as a sorbent with selective properties, its stability in solutions of KCl, Na2CO3, Na2SO4, NaNO3, NaF and Na2S was investigated. In concentrated NaCl solutions, the original composite is transformed into another, as a result of the replacement of \({\text{SO}}_{4}^{{2 - }}\) with Cl– ions. The regenerated polymer is capable of forming a composite again. Using FTIR, SEM EDX and thermogravimetry methods, the changes that occur in the polymer phase during composite formation and its regeneration were studied. It has been shown that the composite has selective sorption properties.
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.
