Abstract: In order to improve the ability of urea formaldehyde resin to adsorb uranium, it was modified with asparagine to synthesize NP resin, which was used to enrich uranium in wastewater and improve the monitoring efficiency of uranium in water. The results showed that, in the case of a F/U molar ratio of 0.8 and an amount of asparagine of 5%, the adsorption capacity of the NP resin was 46.98 mg/g with the temperature, pH and equilibrium time set to 25 ℃, 5, and 210 min respectively.
