前沿科研成果融入水污染控制工程教学——多壳层纳米粒子的制备与高级氧化技术降解四环素

Integrating Frontier Scientific Research into Water Pollution Control Engineering Teaching:Preparation of Multi-shell Nanoparticles and Advanced Oxidation Processes for Degrading Tetracycline

设计了一个多壳层CeO_(2)纳米粒子活化过硫酸盐降解盐酸四环素的水污染控制工程实验。用水热法合成CeO_(2)掺杂的碳微球,然后煅烧得到多壳层CeO_(2)纳米粒子,最后用多壳层CeO_(2)纳米粒子活化过一硫酸盐(PMS)进行盐酸四环素的降解。本实验能够让学生深入了解高级氧化技术的原理,锻炼学生制备纳米粒子和使用仪器设备的能力,认识表征技术,理解多变量实验中控制变量的意义,培养学生的科学素养。

A water pollution control engineering experiment was designed for the activation of persulfate by multi-shell CeO_(2) nanoparticles to degrade tetracycline hydrochloride.CeO_(2) doped carbon microspheres were synthesized by hydrothermal method,followed by calcination to obtain multi shell CeO_(2) nanoparticles.Finally,the multi shell CeO_(2) nanoparticles were activated with persulfate(PMS)for the degradation of tetracycline hydrochloride.This experiment can enable students to have a deep understanding of the principles of advanced oxidation technology,exercise their ability to prepare nanoparticles and use instruments and equipment,understand characterization techniques,understand the significance of controlling variables in multivariate experiments,and cultivate their scientific literacy.
