摘要
介绍了3种碳基吸附剂对水体中铀的吸附特性。大量研究结果显示:溶液pH、离子强度、体系温度、铀初始浓度和接触时间等对吸附材料吸附铀的性能都有很大影响;吸附材料表面不同的官能团是影响其吸附能力的重要因素,表面接枝不同官能团的吸附材料对铀的吸附性能存在明显差异;目前,通过离子印迹、接枝功能化等方式可以对材料进行改性,提高其对铀的吸附性能。
Adsorption properties for uranium of three carbon materials were introduced. Many research results show that the parameters such as aqueous pH, ions strength, temperature, uranium initial concentration and contact time have an effect on sorption properties of the sorbent. Meanwhile, different functional groups grafting on the sorbent have obvious effect on adsorption properties of the sorbent. At present, the sorbents can be modified by ion imprinting and surface grafting method to increase the sorbent sorption properties for uranium.
