摘要: :将玉米秸秆无氧炭化,以葡萄糖为粘合剂掺杂Fe2+水热制备秸秆炭电极,表征了其结构和形貌,考察了电压、时间、pH值对Fe2+炭化电极吸附模拟废水中Zn2+的影响. 结果表明,玉米秸秆与FeSO4×7H2O按质量比1:1所制电极疏松多孔、鼓泡均匀. 在电压14 V、pH值8.0、吸附150 min的条件下,对Zn2+的去除率达88.2%.

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+
