Orthogonal array design for the optimization of stripping Sr(II) from ionic liquids using supercritical CO2

doi:10.1016/j.cjche.2016.05.005

摘要/Abstract

摘要： The strontium ions extracted from the aqueous phase into 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide (C₂mimNTf₂) with dicyclohexyl-18-crown-6 (DCH18C6) was stripped effectively by supercritical CO₂ (sc-CO₂). Hexafluoroacetylacetone (HFAA)-acetonitrile was found to be an excellent modifier of sc-CO₂ to enhance the stripping efficiency. In the orthogonal array design (OAD), OA₂₅ (5⁵) matrix was employed to optimize the stripping of Sr(II) from the DCH18C6-C₂mimNTf₂ system. Effects of five experimental factors:temperature, pressure, concentration of HFAA, static and dynamic extraction times as well as each factor at five-levels on the stripping of Sr(II) were optimized. The effects of these parameters were treated by the analysis of variance (ANOVA). The results showed that Sr(II) could be nearly 100% extracted from the IL phase at 308 K, 30 MPa, 40 min of dynamic extraction and 60 mmol·L^-1 HFAA in acetonitrile, respectively. Finally, the stripping mechanism was studied by ESI-MS.
