Introduction

Increasing demand of precious metals (PMs).

Gradual depletion of high grade ores of PMs.

Essential to recover and reuse of PMs. from secondary resources.

Hence, recycling of e-waste for precious metals has a great importance for conservation and for clean environment

A novel scavenger for precious metal recovery was developed to recover precious metal from WPCB metal leachate

The noble metal scavenger have Good adsorption capacity towards Au(III), Pd(II) and Ag(I). Remarkable selectivity towards Au(III), Pd(II) and Ag(I).

Outstanding recovery of PMs from WPCB leachate in aqua regia.
