Abstract
A method is disclosed of synthesizing θ-alumina/hematite (θ-Al2O3/Fe2O3) composite nanofibers for removing heavy metals from a water source. The method includes preparing a polymer solution, the polymer solution comprising an iron precursor, acetic acid and a polymer; adding a select amount of an aluminum precursor to the polymer solution; and electrospinning the polymer solution and the select amount of the aluminum precursor to form the θ-Al2O3/Fe2O3 composite nanofibers.
