For effective extraction of metal ion from water, the applied ILs should be hydrophobic and preferably containing non fluorinated anions. The hydrophobicity of ILs can be further manipulated by the addition of diluents. To understand extraction of metal ion using binary mixtures of ILs + diluent, it is utmost important to explore different types of interactions exist in the binary mixtures using thermophysical
离子液体(ILs)的结构变异能力为特定应用提供了微调热物理性质的机会。为了从水中有效提取金属离子,所施加的离子液体应为疏水性的,并且最好包含非氟化阴离子。IL的疏水性可以通过添加稀释剂来进一步控制。要了解使用ILs +稀释剂的二元混合物萃取金属离子,利用热物理性质探索存在于二元混合物中的不同类型的相互作用是至关重要的。为此,我们提供了密度,ρ和声速u的实验测量数据用于非质子离子液体(APIL)的二元溶液,即三辛基甲基铵双-(2-乙基己基)磷酸酯[TOMA] [DEHP],三辛基甲基铵双-(2-乙基己基)二乙醇酸酯[TOMA] [DGA],三辛基甲基铵双-(2-乙基己基基)磺基丁[TOMA] [DEHS]在T = 293.15ķ甲苯和十二烷(稀释剂)至328.15 K.等体积的表观摩尔属性V φ,等熵压缩ķ小号,φ和限制性膨胀Ë φ ∞计算和中说明温度,阴离子大小和溶剂性质。两个V φ和
