Abstract

Language:

This study investigates the uptake of uranium (VI) ions using an anion exchanger resin, Amberlite CG-400, in the presence of sulfate anions. The objective was to analyze the impact of various parameters, including pH, contact time, initial concentration of uranium ions, and interference from different anion species (phosphate, chloride, sulfate, nitrate, and fluoride) on the sorption performance of the resin. The methodology involved experiments to determine uranium sorption efficiency across different conditions. Results indicated that uranium ion sorption on the resin significantly occurred at pH 4 and above, with rapid kinetics observed, achieving maximum uptake within a short time. The study also employed isotherm and kinetics models, identifying conformity with Freundlich and pseudo second-order models, respectively, with a maximum sorption capacity (q_max) of 63.29 mg g^-1. The presence of various anions was found to influence uranium sorption, with sulfate ions enhancing the resin's ability to capture uranium, whereas phosphate did not hinder sorption, and the presence of fluoride, nitrate, and chloride led to a decline in resin efficiency.
