针对含锌离子废水的选择性处理问题
研究制备两种含有硫醚与硫脲基的功能性离子液体
对含锌离子废水进行了萃取分析
探讨重金属离子、溶液pH及超声波辅助等其他因素对萃取过程的影响.结果表明两种基团较之传统咪唑离子液体对锌离子的萃取效果(30%~40%)均有着较大的促进作用
其中硫脲基离子液体的萃取率可达75%
硫醚基离子液体萃取率可达90%以上.pH的改变对Zn2+的萃取率影响不大
超声波可加快萃取过程
但对最终萃取率影响较小
研究同时发现官能化离子液体中负离子与Zn2+之间的静电相互作用外
硫醚基对Zn2+还存在较强的路易斯酸碱作用
能够与Zn2+形成稳定配合物.
Aiming at the selective treatment of zinc ion-containing wastewater
this study prepared two functional ionic liquids containing thioether and thiourea groups
extracted and analyzed the zinc ion-containing wastewater
and discussed the influence of other factors such as heavy metal ions
solution pH and ultrasonic assist etc on the extraction process. The results show that the two groups have a greater promotion effect on the extraction effect of zinc ions(30~40%) than traditional imidazole ionic liquids. Among them
the extraction rate of thiourea-based ionic liquids can reach 75%. The liquid extraction rate can reach more than 90%. The change of pH has little effect on the extraction rate of Zn2+. Ultrasound can speed up the extraction process
but has little effect on the final extraction rate. At the same time
it is found that the electrostatic interaction between the anion and Zn2+ in the functionalized ionic liquid has a sulfide group. It also has a strong Lewis acid-base effect on Zn2+ and can form stable complexes with ZnZn2+.
