An Amino-Thiophene Functionalized Metal-Organic Framework on Fabric for Selective Extraction, Recovery, and Passive Sampling of Gold Ions and Nanoparticles.

ABSTRACT: The steadily increasing use of gold and the limited gold reserves have instigated a significant research effort to develop materials with efficient gold recovery. However, most works focus only on the uptake of Au ions, ignoring Au nanoparticles, which are increasingly used in various applications and represent a critical source of Au. Furthermore, the reported gold recovery studies involve powder-form materials that cannot be easily retrieved after the sorption process, thus making them unattractive for real, large-scale applications. The present work reports a Zr-(IV) metal-organic framework (MOF) with a defective microporous structure and amino-thiophene functional groups, which exhibit strong interactions with Au species. The MOF was immobilized on cotton fabric via an in situ method t
