▎ 摘　　要

Functionalized magnetic graphene oxide nanoribbons (MGONRs) composite material was synthesized by hydrothermal treatment method using graphene oxide nanoribbons as raw material, which was formed by longitudinal unzipping of multi-walled carbon nanotubes in oxidizing environment. The morphology and structural properties of MGONRs were characterized by SEM, FT-IR, XRD and VSM and thorium adsorption behavior on MGONRs was investigated. The results showed that thorium adsorption on MGONRs was pH-dependent, endothermic and spontaneous. The adsorption process followed pseudo-second order and Freundlich isotherm model with rapid solid-liquid separation. MGONRs could have practical application in separation and recovery of thorium from aqueous solutions.
