Production of Nanomagnetite by Sol-gel and Mechanical activation procedures

Nowadays environmental standards have made industries innovate new processes for removal of toxic metals. Using iron oxide as an adsorbent is an interesting issue for removal of heavy metals from wastewater. Its magnetic properties allow relatively routine dispersal and recovery of the adsorbent into and from groundwater on industrial processing [1]. In addition, magnetite has strong and specific interactions with heavy metals. In this research, the nanocrystalline magnetite was synthesized by thermal-mechanical activation of hematite and sol-gel method
