□ Title of the thesis: Removal of some chemical and
microbial pollutants from wastewater via biochar/ iron oxide
nano-composite.

This work has been carried out to evaluate the
efficiency of low cost adsorption materials in Fe and Zn
removal from wastewater released from wastewater
treatment plant at Quhafa Al-Fayoum plant works by
activated sludge extended aeration system. This showed by
preparing two composites SCB-BC/ Fe3O4 and RH-BC/
Fe3O4 . The best results showed high removal rates Zn ions
by SCB-BC/ Fe3O4 (97%). The two composites showed equal
removal rates for Fe ions (90%).
□ Key words:
Biochars, nano-magnetite, adsortion.
