摘要

离子对萃取可以通过质子化萃取剂回收阴离子金属离子，例如过硫酸盐和氯化铑离子，质子化萃取剂的结构中含有三级氨基 N 原子。我们将这一技术扩展到溶解在不同矿物酸中的其他阴离子物种。我们研究了硫酸和氢氟酸（H2SO4 和 HF）中的金属阴离子 Zr、Hf、Nb 和 Ta 的萃取。H2SO4 中的 Zr 和 Hf 以及 HF 中的 Zr、Hf、Nb 和 Ta 可以通过使用 NTAamide（次氮基三乙酰胺）、Methylimino-N，N'-dioctylacetamide（MIDOA）和 trioctylamine（TOA）进行离子对萃取来提取。本研究获得了有关它们萃取行为的基本信息。

Preliminary studies on ion-pair extractions of Zr, Hf, Nb, and Ta using extractants having tertiary N atom from H2SO4 and HF

Ion-pair extraction enables the recovery of anionic metal ions, such as pertechnetate and chlorinated rhodium ions, by protonated extractants with tertiary amino N atom in their structures. We expand this technique for other anionic species dissolved in different mineral acids. Extractions of Zr, Hf, Nb, and Ta, metal anions present in sulfuric and hydrofluoric acids (H2SO4 and HF), are examined. Zr and Hf in H2SO4, and Zr, Hf, Nb, and Ta in HF can be extracted by ion-pair extraction using NTAamide (nitrilotriacetamide), methylimino-N, N’-dioctylacetamide (MIDOA), and trioctylamine (TOA). Basic information about their extraction behavior was obtained through this study.
