Selective adsorption and recycle of Cu from aqueous solution by modified sugarcane bagasse under dynamic condition.

Tetraethylenepentamine modified sugarcane bagasse was prepared and applied to test its feasibility in removing and recovering Cu from wastewater under dynamic condition. Results showed that the Cu could be selectively absorbed from wastewater by the modified SCB fixed bed column. To understand the adsorption mechanism, Cd had been selected as the model interfering ion to investigate how co-ions influence the adsorption of Cu on the sorbent.
