Abstract

SCS pincer ligands 1-4 were synthesised, and their ability to extract Pd(II) from HCl and HNO media was studied. The Pd(II) extraction properties of 1-4 were compared with those of commercial extractants (DOS and LIX84-I) in kerosene. 1 and 2 showed superior Pd(II) extractability (E% = 99.9) relative to DOS and LIX84-I from 0.1-8.0 M HCl and to DOS from 0.1-8.0 M HNO and mixed HCl + HNO media. The Pd(II) extraction rate, acid durability, the most suitable organic/aqueous (O/A) phase ratio, and Pd(II) loading capacity of extractants 1, 2, and DOS were evaluated. 1 and 2 exhibited a greater Pd(II) extraction rate and Pd(II) loading capacity than DOS. 1 was very stable in acid media (HCl and HCl + HNO), whereas 2 and DOS deteriorated in HCl + HNO. Selective extraction of Pd(II) by 1 and 2 was achieved from a mixed solution containing Pd, Pt, Rh, rare metals, and base metal ions that simulated the leach liquors of automotive catalysts. The back extraction of Pd(II) and reusability of extractants 1 and 2 were studied. The Pd(II) extraction mechanism of 1-4 was investigated using FT-IR, UV-visible, and NMR spectroscopy.

摘要

SCS 夹持配体 1-4 被合成，并研究了它们从 HCl 和 HNO 介质中萃取 Pd(II)的能力。将 1-4 的 Pd(II)萃取性能与商业萃取剂（DOS 和 LIX84-I）在煤油中的性能进行了比较。1 和 2 表现出相对于 DOS 和 LIX84-I 从 0.1-8.0 M HCl 和相对于 DOS 从 0.1-8.0 M HNO 和混合 HCl+HNO 介质中更高的 Pd(II)萃取能力（E%=99.9）。评估了萃取剂 1、2 和 DOS 的 Pd(II)萃取速率、酸稳定性、最适宜的有机/水（O/A）相比和 Pd(II)负载能力。1 和 2 表现出比 DOS 更高的 Pd(II)萃取速率和 Pd(II)负载能力。1 在酸介质（HCl 和 HCl+HNO）中非常稳定，而 2 和 DOS 在 HCl+HNO 中降解。1 和 2 从模拟汽车催化剂浸出液的含有 Pd、Pt、Rh、稀有金属和贱金属离子的混合溶液中实现了对 Pd(II)的选择性萃取。研究了 Pd(II)的反萃取和萃取剂 1 和 2 的可重复使用性。使用 FT-IR、UV-可见和 NMR 光谱研究了 1-4 的 Pd(II)萃取机理。
