亲水型偕胺肟吸附剂的ARGET-ATRP可控制备及其对铀的吸附性能
Controlled Preparation of Hydrophilic Amidoxime Adsorbent by ARGET-ATRP and Its Adsorption Performance to Uranium
摘要
Abstract
The preparation of adsorbent is the key to the extraction uranium from sea-water .In this paper ,amidoxime (AO) and tBA were grafted onto the polyvinyl chloride (PVC) substrate by electron transfer activated regeneration atom transfer radical poly-merization (ARGET-ATRP) method to form PVC-AO-tBA .The effects of the intro-duction of hydrophilic monomer of tBA on the properties of AO adsorbent were investi-gated by experimental study at different temperatures ,uranium solution concentrations and pH .The results show that under the same conditions ,the adsorption capacity of uranium on PVC-AO-tBA increases from 109 mg/g to 170 mg/g ;the adaptability of the adsorbent to pH is stronger ,and the optimum pH of extraction uranium extends from 6 to 4-6 .The kinetics analysis show s that the adsorption rate also increases significantly .关键词
