Abstract Heavy metal pollution stems from the modern industry is a severe environmental problem. In this work, a highly efficient adsorbent based on starch-graphene oxide architecture (SGO) was fabricated, characterized and employed to scavenge aqueous Pb(Π). The scavenging performance was evaluated, and the interaction mechanism between SGO and Pb(Π) was elucidated. Results indicate, the starch introduction brought performance enhancement, consequently made SGO outperform both single starch and GO in terms of adsorption efficiency. SGO adsorbs 95.83 % of Pb(Π) in 16 min, with adsorption capacity 383.32 mg•g− 1, manifesting some advantages over other analogous adsorbents, such as higher capacity and faster kinetics. The chemical interaction between Pb(OH)+ and C = O, C-O related groups in SGO supported the adsorption, which was a spontaneous, exothermic and entropy increasing process. The adsorption was well described by the Freundlich, pseudo-second-order model and Intra-particle diffusion models, both intra-particle diffusion and chemical interaction were the rate controlling steps. Based on its high adsorption efficiency, SGO may have promising application in heavy metal scavenging from water.
