Abstract

Corn straw was carbonized in a non-oxygen atmosphere to obtain straw carbon, and Fe2+-doped carbon electrode was synthesized by hydrothermal method with glucose as adhesive through the reaction of FeSO4×7H2O with the straw carbon. Its microstructure and morphology were analyzed. The effects of voltage, time and pH value on adsorption removal of Zn2+ from wastewater by the Fe2+ doped carbon electrode were examined. The results show that the electrode has a best adsorption rate of 88.2% when the mass ratio of corn straw carbon to FeSO4×7H2O is 1:1 and under the conditions of adsorption at the voltage of 14 V, 150 min and pH 8.0.

Key words： straw carbonization; glucose; Fe2+; carbon electrode; adsorption; Zn2+
