Heavy Metal Divalent Ions (Cu2+, Zn2+, Cd2+) Removal by Zirconium-based Magnetic Sorbent

Uncontrollable discharge of heavy metals has adversely affected human beings and environment. In this research, zirconium-based magnetic sorbent was synthesized by co precipitation method and explored as a potential sorbent for removal of divalent metal ions; Cu2+, Zn2+, and Cd2+ from aqueous solut...
