surface area and
adsorption abilities as well as increase the cost. So biochar/c-
Fe2O3 composite may be created to obtain properties that cannot
be achieved by any of the components actIn this work, a novel self-assembled magnetic biochar/c-Fe2O3
composite with robust interconnected 3D biochar networks was
fabricated via thermal conversion (pyrolysis) of FeCl3 pre-treated
biomass (cotton wood). The biochar networks can efficiently
prevent the c-Fe2O3 particles from aggregating. In addition, the
biochar/c-Fe2O3 composite is not only an ideal candidate as a
high-efficiency adsorbent to remove arsenic from water but is alsoing alone.
