Key Points

This study aims to develop a robust adsorbent for efficient gold recovery from electronic waste using a covalent organic framework.
Developed a cryptand-based covalent organic framework for extracting Au(III).
Tested the framework in complex acidic leaching solutions for gold recovery efficiency.
Achieved high recovery rates of Au(III) from e-waste leaching solutions.
Demonstrated the framework's stability and effectiveness under acidic conditions.

Implication

Demonstrates effective gold recovery in electronic waste, highlighting environmental solutions.

Abstract

The increasing desire for gold and environmental burden of electronic waste (e-waste) demand robust adsorbents which enables the efficient extraction of trace Au(III) from complex acidic leaching solutions with high...
