SORPTION OF RHENIUM: RESEARCH, METHODS, AND SCIENTIFIC APPROACHES
Main Article Content
Abstract
This article examines the sorption process of rhenium (Re) and its effective methods. Due to the presence of perrhenate ions (ReO₄⁻) in industrial waste and the environment, which pose ecological risks, their efficient removal is one of the key challenges. Various types of sorbents, including activated carbon, ion-exchange sorbents, zeolites, and biomass-based materials, are analyzed. The main mechanisms of the sorption process, such as electrostatic forces, ion exchange, and Van der Waals interactions, are discussed. Furthermore, technologies for rhenium recovery using modern nanomaterials and modified polymers are explored. This review serves as a valuable source of information for research aimed at reducing rhenium's environmental hazards and developing effective purification methods.
