针对传统粉末状锂离子筛在提取盐湖中Li+时受其他离子干扰导致提取效果差的问题,提出一种新型纳米纤维毡的制备方法。首先对纤维毡的结构进行了表征,然后对其性能进行了研究。结果表明,锂离子筛用量为60%时制备的纳米纤维毡可有效吸附溶液中的Li+。在此条件下,纳米纤维毡对Li+的饱和吸附容量为39。7mg·g-1,热解温度为340℃,经过5次循环后,吸附量降至36。8mg·g-1,表现出良好的吸附性能、热稳定性和循环回收性能。将该纳米纤维毡用于实际盐湖水提锂,纳米纤维毡均对Li+表现出良好的选择吸附性能,可在盐湖提锂中发挥重要作用。
Preparation of nanofiber felt materials and study on lithium ion extraction properties
A new type of nanofiber felt is proposed to address the problem of poor extraction efficiency caused by interference from other ions during the extraction of lithium ions from salt lakes using traditional powdered lithium-ion sieves.Firstly,the structure of the fiber felt was characterized,and then their properties were investigated.The results showed that the nanofiber felt prepared with a lithium ion sieve dosage of 60%can effectively adsorb lithium ions in the solution.Under these conditions,the saturated adsorption capacity of the nanofiber felt for lithium ions was 39.7mg·g-1,and the pyrolysis temperature was 340℃.After five cycles,the adsorption capacity decreased to 36.8mg·g-1,demonstrating good adsorption performance,thermal stability,and cycle recovery performance.The nanofiber felt was used for lithium extraction from actual salt lake water,and the nanofiber felt showed good selective adsorption performance for lithium ions,which can play an important role in lithium extraction from salt lakes.
