摘要

利用溶胶-凝胶法将［C8 mim］PF6和二（2-乙基己基）磷酸（HDEHP）固定在固体硅胶复合材料上。离子液体［C8 mim］PF6在反应过程中作为溶剂，为HDEHP提供了一个可以扩散的介质。复合材料对Ce(Ⅲ)的萃取主要取决于HDEHP与金属离子的络合作用。首先利用SEM和红外表征了复合材料的表面形貌和化学成分，然后研究了复合材料对金属离子Ce(Ⅲ)的吸附性能。考察了不同复合材料、振荡时间对Ce(Ⅲ)吸附性能的影响。结果表明，该复合材料对Ce(Ⅲ)有较好的萃取效果。用硅的复合材料进行金属离子的固液萃取可以是一种有效的方法。

Abstract

The silica materials which were composed of ionic liquids and di(2-ethylhexyl) phosphoric acid (HDEHP) for Ce(Ⅲ) extraction were prepared via a sol-gel method. The hydrophobic ionic liquid 1-octyl-3-methylimidazolium hexafluorophosphate (［C8 mim］PF6) was used as solvent medium. Ionic liquid was stably doped into the silica gel matrix providing a diffusion medium for HDEHP. The extraction of Ce(Ⅲ) was mainly due to the complexation of metal ions with HDEHP doped in the solid silica. In this study

composite materials were characterized by using SEM and FTIR to determine the surface topography and chemical constituents. Then

sorption behavior of Ce(Ⅲ) on composite materials was studied under ambient conditions by using a batch technique. Different composite materials and effect of shaking time on Ce(Ⅲ) sorption were also investigated. The results indicate that composite materials have higher removal efficiencies and excellent stability for metal ions extraction. The solid-liquid extraction by silica materials could be regarded as an effective method for metal ions extraction.
