Synthesis and use of nanomagnetic mno2 adsorbent for removing pb(ii) and cd(ii) ions from acid aqueous solutions

Abstract

A nanoadsorbent based on delta-MnO2 and Fe3O4 was synthesized and assessed as an adsorbent for removing some heavy metals from acidic aqueous solution. The delta-MnO2 adsorbent was prepared in aqueous alkaline medium using an oxidative precipitation meth
