摘要/Abstract

摘要： 针对江西宜春某锂尾矿带来的铍(Be)、铊(Tl)等重金属污染问题,研究成功制备了一种以碳纳米管为
基体的功能化纳米复合材料。采用X 射线光电子能谱(XPS)、傅里叶变换红外光谱(FT-IR) 和扫描电子显微镜
(SEM)对材料进行了表征,证实其表面成功引入了多种活性官能团。系统吸附试验表明,该材料对Be2+ 和Tl+ 具有快
速且高效的吸附性能:吸附过程在30 min 内即可达到平衡;当材料投加量为0. 6%时,对Be2+的去除率达94. 5%,而对
Tl+仅需0. 3%的投加量即可达到92. 5%的去除率;溶液近中性(pH≈7)条件最有利于吸附。基于《固体废物浸出毒
性浸出方法硫酸硝酸法》(HJ/ T 299—2007)标准的浸出毒性测试验证了该材料能有效固化尾矿中的重金属。研究为
锂尾矿的重金属污染治理提供了一种具有应用潜力的吸附剂与可行技术方案。

Abstract: To address the heavy metal pollution (beryllium (Be) and thallium (Tl)) caused by a lithium tailings site in
Yichun,Jiangxi Province,a functionalized nanocomposite material with carbon nanotubes as the matrix was successfully prepared.
The material was characterized using X-ray Photoelectron Spectroscopy (XPS),Fourier Transform Infrared Spectroscopy
(FT-IR),and Scanning Electron Microscopy (SEM). These characterizations confirmed that multiple active functional groups
were successfully introduced onto the material's surface. Systematic adsorption experiments showed that the material exhibits
rapid and efficient adsorption performance for Be2+ and Tl+ . The adsorption process reaches equilibrium within 30 minutes.
When the material dosage is 0. 6%,the removal rate of Be2+ reaches 94. 5%. For Tl+ ,a dosage of only 0. 3% achieves a removal
rate of 92. 5%. A nearly neutral solution (pH≈7) is most favorable for adsorption. Leaching toxicity tests,conducted in accordance
with the standard Solid Waste-Leaching Toxicity Leaching Method-Sulfuric Acid-Nitric Acid Method (HJ/ T 299—
2007),verified that the material can effectively solidify heavy metals in the tailings. This study provides a promising adsorbent
and feasible technical solution for the remediation of heavy metal pollution in lithium tailings.
