摘　　要：为解决莠去津的大量使用而导致的环境污染问题,本研究通过水热、煅烧法成功制备出负载型钴基催化剂复合材料Co1.5-玉米秸秆生物炭并构建了过一硫酸盐高效降解体系。通过透射电子显微镜、X射线衍射光谱和比表面积及孔径表征,获得Co1.5-玉米秸秆生物炭催化剂的结构特征信息。对Co1.5-玉米秸秆生物炭/过一硫酸盐体系降解性能和影响因素研究发现,当Co1.5-玉米秸秆生物炭浓度为0.010 g/L、过一硫酸盐浓度为0.075 g/L时,Co1.5-玉米秸秆生物炭/过一硫酸盐体系30 min对莠去津的降解率达到97.96%。本研究为新型高效、绿色催化剂的研发提供了新的制备方案,并为实际废水的治理提供了科学参考。In order to solve the environmental pollution problem caused by the massive use of atrazine,this study successfully prepared a loaded cobalt-based catalyst composite Co1.5-Cornstalk biochar and constructed an efficient degradation system of peroxymonosulfate by hydrothermal and calcination method.Information on the structural characteristics of the Co1.5-Cornstalk biochar catalysts was obtained by transmission electron microscopy,X-ray diffraction spectroscopy,and specific surface area and pore size characterization.Further investigation was carried out on the degradation performance of the Co1.5-Cornstalk biochar/peroxymonosulfate system and the factors affecting the degradation of atrazine.The degradation rate of Co1.5-Cornstalk biochar/peroxymonosulfate system for atrazine reached 97.96%in 30 min at the concentration of 0.010 g/L of Co1.5-Cornstalk biochar and 0.075 g/L of peroxymonosulfate.This study provided a new preparation strategy for the research and development of new efficient and green catalysts,and a scientific reference for the treatment of real wastewater.
