Mixed-valence molybdenum oxide as a recyclable sorbent for silver removal and recovery from wastewater

Abstract

Silver ions in wastewater are a major health hazard, and there is an urgent need to develop methods to reliably extract them. Here, the authors show that mixed-valence molybdenum oxide can selectively adsorb and reduce Ag+ from wastewater and be easily recycled while maintaining high selectivity towards Ag+.
