Synthesis of Magnetic Biochar for Efficient Removal of Cr(III)‎ Cations from the Aqueous Medium

الملخص EN

Porous biochars obtained from coniferous woods, and magnetic biochars based on them, which showed high sorption properties when extracting Cr(III) from aqueous solutions (from 0.005 to 0.0125 mol/L), were studied.

The adsorption properties of the magnetic biochar are compared with the initial biochar.

It has been established that the preparation of materials by the method of pyrolysis and subsequent treatment in a plasma reactor makes it possible to bring the samples under study into a number of promising adsorbents for the extraction of chromium from aqueous solutions.
