▎ 摘　　要

A novel 3D composite, graphene oxide-starch (GO-SS), was developed by the hydrothermal treatment of SS and GO. SS was uniformly assembled into the 3D network of GO, and the resultant hybrid composite with the mass ratio of 3:1 for GO and SS possessed higher specific surface area (303.5398 m(2) g(-1)) and smaller radius of the micro-pores (1.78 nm). And this porous 3D graphene oxide-SS composite exhibited high adsorption capacities of 108.68 mg g(-1), 32.12 mg g(-1), 46.28 mg g(-1), 41.76 mg g(-1) and 38.168 mg g(-1) for Pb(II), Cu(II), Cd(II), Yb(III) and Nd(III) from aqueous solutions, respectively.
