摘要：
Graphene sponge (RGO) and graphene magnetic particles (MGO) were successfully prepd. and used for removal of Cu2+ ions from their aq. solns. The effects of pH value, adsorption time and adsorbent dose on the adsorption efficiency of Cu2+ on RGO and MGO were compared. At pH 5, the initial Cu2+ concn. 10 mg/L, and the adsorbent concn. 0.6 g/L, the adsorption was most efficient. The removal rate of Cu2+ by RGO (99.5%) was higher than that of MGO (94.1%), because of overlapping the graphene layers in MGO and an increase in ion diffusion resistance in the later stage. The graphene materials were recycled. After 6 cycles of adsorption, the removal rate was still 92%.
