摘要

本工作从麦库本矿床氧化褐煤中分离得到一种基于腐殖酸（HA）的吸附剂。通过红外光谱对腐殖酸的研究表明，吸附剂中存在各种官能团（OH-、COOH-），这些官能团可以与金属进行离子交换反应。腐殖酸已被测试为钕的吸附剂。在静态条件下从硝酸盐溶液中吸附钕。研究发现，当吸附时间为30min，溶液pH为1.0时，钕的吸附效率为95.5%。使用基于腐殖酸的吸附剂从溶解电子废物（钕磁体）获得的溶液中分离钕。吸附钕后吸附剂表面的SEM分析和图谱显示吸附剂表面不存在钕。

Sorption of Neodymium from Nitrate Solutions by Humic Acids-Based Sorbent

This work obtained a sorbent based on humic acids (HA) isolated from oxidized brown coals of the Maikuben deposit. The study of humic acids by IR spectroscopy showed the presence of various functional groups (OH-, COOH-) in the sorbent, which can enter into ion-exchange reactions with metals. Humic acids have been tested as a sorbent for neodymium. Neodymium sorption was carried out under static conditions from nitrate solutions. It was found that with a sorption time of 30 min and a solution pH is 1.0, the sorption efficiency of neodymium is 95.5%. A sorbent based on humic acids was used to separate neodymium from a solution obtained by dissolving electronic waste (neodymium magnet). SEM-analysis and mapping of the sorbent surface after neodymium sorption showed that neodymium was absent on the sorbent surface.
