We reported the utility of 1-octanol/benzene mixed solvents for the partition of benzoic acid and the extraction of copper(II) with benzoic acid. As benzene has been pointed out to possess carcinogenic activity, we selected octane as a non-solvating solvent in the place of benzene and investigated the solvent extraction equilibrium for the octane/1-octanol mixed solvent systems.The partition of 8-quinolinol between the octane/1-octanol mixed solvents with the various mixing ratio and water, and the extraction of aluminum, gallium, indium and iron(III) with 8-quinolinol using these mixed solvents were carried out. We found some new and interesting results on the analysis of the extraction equilibrium for these extraction systems. Protonated 8-quinolinol(oxine) cation(H_2O_x+) was found to be extracted by various inorganic anions such as chloride, perchlorate and nitrate in the lower pH regions, and the partition constant of oxine molecule was quantitatively elucidated by the regular solution theory.On the extraction of aluminum, gallium, indium and iron(III) with oxine, the partition constants of M(0_x)_3 complex were successfully determined. The high correlation between the partition constants of oxine and the respective extracted species were found. In addition, the result, which suggests the electrical condensation at the complex formation, was obtained.Extraction of 2-( 2-pyridylazo)-1-naphthol-4-sulfonate anion with solvated hydroxonium ion was carried out using octane/1-octanol mixed solvents. The extraction equilibrium for the systems was analyzed in detail in order to examine the extraction mechanism. 2-(2-Pyridylazo)-1-naphthol-4-sulfonate was found to be extracted with hydroxonium ion solvated by three 1-octanol molecules as an ion-pair. The extraction and partition constants of the ion-pair of 2-(2-pyridylazo)-1-naphthol-4-sulfonate anion with solvated hydroxonium ion were estimated in the octane/1-octanol mixed solvent systems.

我们报道了正辛醇/苯混合溶剂用于苯甲酸的分配和苯甲酸萃取铜（II）的效用。由于苯具有致癌性，本文选择辛烷代替苯作为非溶剂化溶剂，研究了辛烷/正辛醇混合溶剂体系的萃取平衡，考察了8-羟基喹啉在不同配比的辛烷/正辛醇混合溶剂与水之间的分配，以及铝、镓、使用这些混合溶剂进行铟和铁（III）与8-羟基喹啉的反应。我们发现了一些新的和有趣的结果，对这些萃取体系的萃取平衡分析。在较低的pH值范围内，8-羟基喹啉（8-羟基喹啉）阳离子（H_2O_x ~+）可被氯离子、高氯酸根和硝酸根等无机阴离子萃取，用正规溶液理论定量地确定了8-羟基喹啉分子的分配常数，并成功地测定了8-羟基喹啉萃取铝、镓、铟和铁（Ⅲ）时M（0_x）_3配合物的分配常数。在正辛烷/正辛醇混合溶剂中，2-（2-吡啶偶氮）-1-萘酚-4-磺酸根阴离子被溶剂化的氢氧鎓离子萃取。详细分析了体系的萃取平衡，探讨了萃取机理。发现2-（2-吡啶偶氮）-1-萘酚-4-磺酸盐能被三个正辛醇分子溶剂化的氢氧鎓离子萃取。在正辛烷/正辛醇混合溶剂体系中，估算了2-（2-吡啶偶氮）-1-萘酚-4-磺酸根阴离子与溶剂化氢氧鎓离子的离子对萃取和分配常数。
