FIELD: chemistry.
SUBSTANCE: proposed material comprises a porous ceramic substrate with a porosity of 35-85% and zero valent iron nanoparticles formed in the porous ceramic substrate. The porous ceramic substrate has 2-10 microns micropores and a loose amorphous silicon-iron-carbon structure formed inside of each micropore. At least 25 wt % of the ceramic component constituting the porous ceramic substrate is kieselguhr. The loose amorphous silicon-iron-carbon structure in the micropores can form an adsorption film after water adsorption. A method for material production is proposed.
EFFECT: obtaining of an efficient sorbent for arsenic ions removal with an ability to adapt to changes in water quality and chemical environment.
