Abstract

The metal ion extractant (HDEHP) that is commonly employed in liquid membrane extraction has been shown to stabilise Ag and Cu nanoparticles in oil media of size 5 and 10 nm, respectively. The particle are formed by reduction of the metal salts of HDEHP that are oil soluble and shown by SANS to form small reversed micelles of radius approximately 1 nm. The extractant is also effective at stabilising particles of similar size in an oil phase when the metal ion (e.g., AgNO3) is reduced in a coexisting aqueous phase.

摘要

常用于液膜萃取的金属离子萃取剂（HDEHP）已被证明能分别在尺寸为5纳米和10纳米的油相中稳定银和铜纳米颗粒。这些颗粒是通过还原HDEHP的金属盐形成的，这些金属盐可溶于油，并且小角中子散射显示它们形成半径约为1纳米的小反胶束。当金属离子（如硝酸银）在共存水相中被还原时，该萃取剂在稳定油相中类似尺寸的颗粒方面也很有效。
