Abstract
A method is proposed for producing a magnetic carbon material based on the deposition of a labile iron compound on a carbon matrix and its subsequent thermolysis with the formation of magnetite. The method is implemented by applying magnetite to activated carbon BAU-A during the decomposition of iron(II) oxalate. The production of a magnetic carbon material has been confirmed by X-ray fluorescence and X-ray phase analysis. The porous carbon material modified by this method retains its sorption characteristics.
