Synthesis of industrial solid wastes/biochar composites and their use for adsorption of phosphate: From surface properties to sorption mechanism

This paper demonstrates the synthesis of industrial solid wastes /biochars. The produced materials were characterized by means of X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR). The composites were investigated for the phosphate removal from the aqueous solution. The effect of pH on removal rate was studied in the range from 3 to 12. The kinetic experimental data...
