臭氧的制备与性质研究实验设计与实践

Design and Practice of Research-oriented Experiment:Preparation and Properties of Ozone

在自行研制的臭氧分流式供气实验装置上,以有机磷农药草甘膦为对象,设计了一套研究臭氧氧化性能的教学实验方案。实验内容包括臭氧发生量的测定、草甘膦降解产物正磷酸根离子的测定、草甘膦的转化率计算以及草甘膦转化率随氧化反应时间的变化曲线的绘制。通过实验,学生能深刻认识和掌握臭氧的氧化性能及其研究方法。该研究型实验设计新颖、实用,已经成功用于本科生环境化学教学实验。

This paper designed a teaching experiment program to study oxidability of ozone by using self-made distributary ozone generator and choosing organophosphorus pesticide glypho- sate as an object. The experiment program included the determination of the amount of ozone, the determination of orthophosphate ions degraded from glyphosate, the conversion of glyphosate to orthophosphate ions, and the conversion curve of glyphosate degradation with time. Through this experiment, students could deeply understand and master the oxidation properties of ozone and its research methods. The research-oriented experiment was innovative and practical, and has been successfully used in teaching experiment of environmental chemistry for undergraduate.
