Micro, Sono, Photocatalytic Degradation of Eosin B Using Ferric Oxide Doped with Cobalt

Abeer Sharfalddin, Eman Alzahrani & Mohamad Alamoudi · Chemical Science International Journal · 2016

Eosin B dye is usually used for staining in biology; the stain is harmful if swallowed, smelt, or absorbed through skin. Some researchers have tried to remove it by adsorption, but few have attempted for a complete degradation. In this study, cobalt doped iron oxide (Co-Fe2O3) po...
