In this work, a novel xonotlite nanocomposite was synthesised with abandoned eggshell by hydrothermal method, and organic-modified with toluene diisocyanate (TDI) for the removal of Pb(II) and Cd(II) from wastewater. The xonotlite and organic-modified xonotlite were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunner-Emmet-Teller (BET) and Fourier transform infrared spectroscopy (FTIR) methods. The effect of solution pH, contact time, adsorbent dose, and initial concentrations were also investigated. The organi...
