Abstract

The Al₂O₃–SiO₂-BFS (AS-BFS) solid adsorbent was developed from blast furnace slag (BFS). The potentiality of the AS-BFS for uranium ion removal from an aqueous medium, via the batch method, was explored and disused in terms of dynamic and isothermal properties. The sorbent exhibited good reusability, a high capacity for uranium ions, and a good specific surface area. The results showed that the sorbent evacuated uranium at about 88.5 mg/g. The sorbent represents a promising waste-derived substitute for other sorbents for water treatment.

一种从工业炼铁渣中提取的用于脱铀的简便且经济高效的吸附剂

摘要

Al ₂ O ₃ -SiO ₂ -BFS (AS-BFS) 固体吸附剂是从高炉矿渣 (BFS) 中开发出来的。在动态和等温特性方面探索并废弃了 AS-BFS 通过批量方法从水性介质中去除铀离子的潜力。该吸附剂具有良好的可重复使用性、对铀离子的高容量和良好的比表面积。结果表明，吸附剂以约 88.5mg/g 排出铀。该吸附剂代表了一种有前途的废物衍生替代品，可替代其他用于水处理的吸附剂。
