设计了改性粉煤灰用于吸附废水中刚果红的本科教学实验。以氢氧化剂为活化剂,通过焙烧-水热法对粉煤灰进行改性。采用红外光谱对改性前后的煤粉灰结构进行了表征,并研究了改性后的粉煤灰对废水中刚果红的吸附性能。不仅解决了固废问题,又能缓解水环境污染问题。通过本实验可以提高学生的实验操作和科研思维能力,培养学生的综合实践能力、绿色环保意识和节能减排发展观,为学生进一步开展科学研究奠定坚实的基础。

An undergraduate teaching experiment was designed for the adsorption of Congo red in wastewater by modi⁃fied coal fly ash.In the experiment,fly ash was modified by roasting-hydrothermal method with KOH as activator.The structure of coal fly ash before and after modification was characterized by infrared spectrum.The adsorption perfor⁃mance of modified coal fly ash for Congo red in wastewater was studied.The experiment solves the problem of solid waste and alleviates the problem of water environment pollution.This experiment can improve students′ability of experi⁃mental operation and scientific research thinking.This experiment also can cultivate students′comprehensive practical ability,green environmental awareness and the concept of development of energy conservation,which lays a solid foun⁃dation for students to carry out further scientific research.
