Zero-valent iron/siderite composites for high-efficiency Se(IV) capture from aqueous media: performance characterization and mechanism elucidation
79Se is one of the key fission products in spent fuel, with a half—life of 6.5 × 104 a. Due to its high mobility and minimal solubility constraints, it readily leaches into groundwater, causing extensive contamination and posing grave risks to ecosystems and human well-being. In this work, the removal of Se(IV) was studied by using FeCO3 as the carrier. Zero-valent iron/siderite (Fe0/FeCO3) composite materials were prepared by simple and economical ball milling method and liquid phase reduction method, and the removal of Se(IV) in aqueous solution was studied. The results showed that Fe0/FeCO3 had unique advantages such as easy synthesis, large specific surface area and high adsorption capacity. It is expected to be used as a chemical barrier active material to block the migration of soluble variable nuclides represented by 79Se, and to remove Se(IV) in geological disposal repositories of high-level radioactive waste.
