Thermochemical conversion of garden waste to biochar was carried out to prepare a green adsorbent for the removal of Cs, Cu, Ni, and Pb, which was characterized by XPS, SEM–EDX, and FT-IR analyses. The biocharˊs adsorption capacity was 20.5(Cs), 25.2(Cu), 12.4(Ni), and 45.9(Pb) mg g −1 and demonstra...
