研究了以4% n-正-辛基苯胺为溶剂从8 M盐酸中萃取锡的新方法。用邻苯二酚紫分光光度法测定有机相中的锡（IV）。在7 ~ 10 M盐酸范围内可定量提取。当n-正辛苯胺在二甲苯中的浓度在0.05 ~ 20%范围内变化时，最佳浓度为0.03%。在苯和二甲苯等稀释剂中，甲苯被发现是一种有效的稀释剂。研究了振荡时间、金属离子浓度、盐析剂等因素的影响。
A novel method has been developed for the solvent extraction of tin(IV) from 8 M hydrochloric acid with 4% N-n-octylaniline. Tin(IV) from the organic phase was determined spectrophotometrically with pyrocatechol violet at 550 nm. Extraction was found to be quantitative in the range of 7–10 M hydrochloric acid. When the concentration of N-n-octylaniline was varied from 0.05–20% in xylene, it showed that optimum concentration was > 3%. Amongst diluents like benzene and xylene, toluene was found to be an effective diluent. Effect of shaking time, concentration of metal ion, and salting out agents was studied.
Tolerance limits of various diverse ions were determined by masking interfering cations. Tin(IV) was separated from associated elements in its binary mixture with Se(IV), Sb(III), Bi(III), Pb(II), Au(III), Cu(II) and Zn(II) and from its ternary mixtures with Sb(III), Bi(III) and Cu(II), Au(III). The proposed method was applied for separation and determination of tin(IV) in tin bearing alloys and foodstuffs.
