本实验运用连续的电去离子技术选择性的分离稀溶液中的Cu^(2+)和Co^(2+)。对工作电流,原水流量和以EDTA为络合剂的添加等因素对混合离子分离效果的影响进行了考察。实验结果表明,EDI在工作电流为200 m A,原水流量为60 m L/min的条件下运行,通过向原水中添加络合剂EDTA并且保证其与溶液中的Cu^(2+)和Co^(2+)完全络合,可以得到最佳的分离比37.92。利用EDI过程从二元混合液中选择性分离重金属离子是一种很有前途的方法。
Organic salts such as spiro-(1,1')-bipyrrolidinium tetrafluoroborate([SBP][BF4]) dissolved in liquid acetonitrile(ACN) are a new kind of organic salt solution,which is expected to be used as an electrolyte in electrical double layer capacitors(EDLCs).To explore the physicochemical properties of the solution,an all-atom force field is established on the basis of AMBER parameter values and quantum mechanical calculations.Molecular dynamics(MD) simulations are carried out to explore the liquid structure and physicochemical properties of [SBP][BF4] electrolyte at room temperature.The computed thermodynamic and transport properties match the available experimental results very well.The microscopic structures of [SBP][BF4] salt solution are also discussed in detail.The method used in this work provides an efficient way of predicting the properties of organic salt solvent as an electrolyte in EDLCs.
