摘　　要：本文采用简单的一步热聚合法制备了钴掺杂碳基材料Co_(3) O_(4)-g-C_(3) N_(4),并对其作为吸附剂的性能进行研究。所制备的材料通过XRD、XPS、BET对晶体结构、形貌、价态分布、比表面积以及孔径分布进行表征分析,实验以甲基橙为目标污染物进行吸附,其最大平衡吸附容量为118.83mg/g。Co_(3) O_(4)-g-C_(3) N_(4)吸附剂对甲基橙溶液吸附的动力学符合准二级动力学模型,吸附等温线符合Langmuir等温线。This work mainly focused on optimizing the preparation conditions of the adsorbent,using a simple one-step thermal polymerization method to prepare cobalt doped carbon based adsorbent.The crystal structure,morphology,valence distribution,specific surface area,and pore size distribution of the adsorbent were characterized and analyzed.Combined with XRD and XPS characterization data,the adsorbent material can be named Co_(3) O_(4)-g-C_(3) N_(4).The experiment used methyl orange as the target pollutant for adsorption,with a maximum equilibrium adsorption capacity of 118.83 mg/g.The adsorption kinetics of Co_(3) O_(4)-g-C_(3) N_(4) adsorbent on methyl orange solution conforms to the quasi second order kinetic model,and the adsorption isotherm conforms to the Langmuir isotherm.
