壳聚糖季铵盐的制备及其对铀的吸附性能研究
Synthesis and Adsorption Performance for Uranium of Chitosan Quaternary Ammonium Salt
摘要
Abstract
The spherical chitosan quaternary ammonium salt which is a kind of chitosan matrix strong alkaline adsorbent was prepared by the reactions of chitosan with glutaraldehyde ,epichlorohydrin , trimethylamine aqueous solution in turn .The adsorbent was characterized by infrared ,thermal analysis , and its adsorption performance for uranium were examined .The prepared chitosan quaternary ammonium has good adsorption effect for uranium in the solution containing low concentration of uranium .For the uranyl wastwater from a certain uranium mine whose initial concentration of uranium is 2 mg/L ,the uranium concentration can be dropped below 0 .05 mg/L by shaking adsorption with the adsorbent and meets the wastewater discharge standard .关键词
