Antimonate and antimonite adsorption by a polyvinyl alcohol-stabilized granular adsorbent containing nanoscale zero-valent iron.

Highlights: [•] For stability and functional excellence, nanoscale Fe0 was stabilized by PVA. [•] PVA–Fe0 composites were fabricated into granules to use as adsorbents for Sb removal. [•] Sb(III) and Sb(V) adsorption on the granules was systematically evaluated. [•] Sb(III)/Sb(V) were chemically bound onto magnetite, the active phase on granules. [Copyright &y& Elsevier]
