摘要: 用天冬酰胺对脲醛树脂进行改性,合成天冬酰胺改性类蛋白氨基螯合树脂(NP树脂),用于废水中铀的富集,以提高水中铀的监测速度。结果表明:在F/U摩尔比为0.8,天冬酰胺加入量为5%的前提下合成NP树脂,该树脂在25 ℃、pH值约为5、平衡时间为210 min时其吸附容量为46.98 mg/g。

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.

Key words: NP Resin, Uranium, Enrichment
