Abstract:
A novel adsorbent GO-TETA-DAC was synthesized by using dialdehyde cellulose (DAC) grafted graphene oxide (GO) with triethylenetetramine (TETA) acted as cross-linking reagent. The product was characteristics by FT-IR, BET and SEM, results proved the preparation process was successful. GO-TETA-DAC was applied to disposal Cu (II) and Pb (II) ions from aqueous solution and achieved excellent performance. The maximum adsorption capacity 65.1 and 80.9 mg/g for Cu(II) and Pb(II) when pH was 5.0. Adsorption isotherm and kinetics revealed the adsorption process complied with Langmuir model and pseudo-second-order model. Furthermore, the reusability of GO-TETA-DAC was also explored, the adsorption efficiency can still over 77% even after four times of recycling.
