摘　　要：将科研成果与创新创业实践教学相结合,设计实施创新综合探究实验,以虾壳为原料制备虾壳生物质炭,用于活化过硫酸盐降解2,4-二氯酚。实验结果表明,虾壳生物质炭在酸性和中性条件下可以有效活化过硫酸盐去除2,4-二氯酚,去除率可达96%。通过该实验,学生能够掌握纳米材料的制备、表征等基本实验技能,能够对数据进行处理和分析,树立“以废治废”理念,增强解决实际问题的能力,提高创新意识。The innovation comprehensive experiment is designed by introducing research results into experimental course.Shrimp shell biochar is prepared by one-step pyrolys is of shrimp shell and used to activate persulfate to remove 2,4-dichlorophenol.The results show that pH has little influence on the removal rate of 2,4-dichlorophenol reach to 96%at acidic and neutral conditions.Through this experiment,students can establish the concept of"treating waste with waste",and master the method of preparing nano-materials,characterization technology,data analyzing and other experimental skills.In addition,this experiment can improve students'awareness of innovation and the ability to apply what they have learned to solve practical problems,and improve their scientific innovation ability.
