杨木屑多孔碳的制备及其对磺胺甲恶唑吸附性能研究

Study on the Removal of Sulfamethoxazole from Modified Poplar Chip Porous Carbon

以杨木屑为原料,氯化锌为活化剂,在改变碳化温度的条件下制备多孔碳,探究了多孔碳对环境中的磺胺甲恶唑(SMX)的吸附效果。利用扫描电镜、傅里叶红外等结构表征解释了多孔碳对磺胺甲恶唑的吸附机理。结果表明,在800℃下活化的多孔碳拥有更多孔隙,含有丰富的含氧官能团,更高的碳化程度和芳香性,对水中与土壤中的磺胺甲恶唑的吸附效果更好。研究证明杨木屑多孔碳是去除环境中磺胺甲恶唑的优秀材料。

Activated porous carbon was prepared from wood chips and zinc chloride at different temperatures to study its adsorption effect on SMX in the environment.The adsorption mechanism of porous carbon was explained by SEM and XRD.Results The porous carbon at 800℃has more pores,more oxygen-containing functional groups,higher carbonization degree and aroma,and better adsorption effect of sulfamethoxazole in the environment.The porous carbon of poplar sawdust was proved to be an excellent material for removing sulfamethoxazole from the environment.
