The main aim of this research work is to achieve alumina and boron doped alumina nanofibers and apply these nanofibers for waste water treatment. Alumina and boron doped alumina nanofibers were applied for the removal of lead, cadmium, copper, zinc, nickel from 10 ppm of each model mixture solutions. Removal of lead, cadmium, copper, zinc and nickel in waste water and mercury from sea water was carried out with alumina and boron doped alumina nanofibers.
