摘要
介绍了纤维基吸附剂及其制造方法和应用实施情况。主要涉及高比表面纤维、聚合物吸附剂辐射接枝技术、海上作业以及回收铀的洗脱与纯化处理,并对纤维基吸附剂海水提铀的成本作了分析和说明。指出:近年来,国际上采用纤维基吸附剂从海水中提铀技术已取得了长足进展,开展这一方面的研究具有实际的技术经济效益和环境意义;建议我国尽快启动此项研究活动。
This article introduces fiber based adsorbents and its manufacturing method as well as the application. Particularly, it mainly includes fibers with high surface area to weight rate, radiation gaffing of polymeric adsorbents, marine experiment as well as elution and purification of recovering uranium. It also analyzes the cost in extraction of uranium from seawater. In recent years, there is a significant progress in technology in extraction of uranium from seawater by adopting fiber based adsorbents, and the analysis would bring the techonlogical and economic benefit as well as the environmental improvement. It is suggested that China should start R＆D in this respect as soon as possible.
