Sonication enhanced removal of nickel and cobalt ions from polluted water using an iron based sorbent

Abstract

The effect of sonication time on removal efficiency of Ni 2+ and Co 2+ from wastewater in the presence of zero valence iron (ZVI) nanoparticles is described. The results showed that the presence of cobalt ions in the solution enhances the removal efficiency of nickel by ZVI nanoparticles to about 64 which is one of the advantages of this protocol. © 2013 Zari Hooshyar et al.
