Synthesis and Sorption Properties of Lithium Aluminosilicate

Abstract—The article presents data on the synthesis of nanostructured, X-ray amorphous lithium aluminosilicate, with a Si : Al ratio of 3 : 1. The composition, morphology, and thermal behavior were studied. The sorption isotherm of Cs⁺ ions was obtained under static conditions with a ratio of T : L = 1 : 400. The maximum sorption capacity, degree of extraction, and distribution coefficients of cesium were determined. Data on the sorption kinetics of Cs⁺ ions were obtained at temperatures 30 and 60°C, and the activation energy of the sorption process and diffusion coefficients were calculated.

期刊介绍： Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
