摘要:本研究将Co3O4与生物炭进行有机结合,合成一种不溶于水的BC- Co3O4催化材料作为非均相催化剂,然后进行Co3O4催化PMS降解氧氟沙星实验,分别探讨PMS浓度对降解效果的影响,Co3O4投加量对降解效果的影响,温度对降解效果的影响,初始pH对讲解效果的影响。我们发现使用此种高级氧化技术对水中的氧氟沙星去除效果显著,投加量、温度、pH的提高均对实验的降解效率有促进作用。过渡金属离子钴活化过硫酸盐/过硫酸氢盐的反应可在常温下快速进行,无需外加能量,生物炭拥有良好的孔隙结构和吸附性能,制备工艺简单、价格低廉,回收利用性好,因此可视为理想的载体物质,BC- Co3O4催化材料作为非均相催化剂显示出极大的优越性,更具发展潜力。26636 毕业论文关键词:钴;高级氧化技术;非均相;生物炭;水污染处理技术
Biochar supported Co3O4 to activate PMS for degrading ofloxacin in water
Abstract:This research will combine Co3O4 with biochar to make a synthesis of water-insoluble heterogeneous catalyst materials,and to activate PMS for degrading ofloxacin in water. Respectively discuss the influence of PMS,Co3O4 dosage,temperature and initial pH on the degradation. We found that the use of this advanced oxidation technology in water removal efficiency of ofloxacin significantly, dosage, temperature, pH improve the degradation efficiency of the experiment. The transition metal ions cobalt activated persulfate / hydrogen sulfate reaction can be performed at room temperature, without external energy, biochar has pore structure and good adsorption properties, simple preparation process, low cost, recycling is good, so it can be regarded as an ideal carrier material, BC- Co3O4 as catalytic materials the heterogeneous catalyst showed great superiority, greater development potential.
