Abstract:
1. A method of synthesizing carbon-magnetite nanocomposites, comprising the steps of: (a) dissolving a first amount of an alkali salt of lignosulfonate in water to form a first solution; (b) heating the first solution to a first temperature; (c) adding an amount of iron sulfate (FeSO (d) heating the second solution at a second temperature for a first duration of time effective to form a third solution of iron lignosulfonate; (e) adding an amount of 1N sodium hydroxide (NaOH) to the third solution of iron lignosulfonate to form a fourth solution with a first pH level; (f) heating the fourth solution at a third temperature for a second duration of time to form a first sample; and (g) subjecting the first sample to a microwave radiation for a third duration of time effective to form a second sample containing a plurality of carbon-magnetite nanocomposites.
