Abstract

Biochar, defined as the carbon residue obtained from the thermal decomposition of biomass, can be used for a wide variety of applications, such as soil amendment, adsorption for water and air pollutants, catalysis, electronic industry or hydrogen storage. For the removal of pollutants from water, the association of biochar with magnetic particles inside a composite material enables the sorbent to be easily separated by magnetic filtration from the decontaminated water after the adsorption step [1]. In this work, the chemical and physical properties of a magnetic biochar obtained from a biorefinery residue have been investigated, with the association of a classical sorption study to a physical study for the understanding and optimization of the magnetic separation.
