实验教学用光催化氧化装置的研制和应用

Development and application of photo-catalytic oxidation reactor for undergraduate teaching level

光催化氧化作为一种能有效去除难降解有机物的技术方法,在污染治理与控制中越来越受到重视,并在实际工程中得到较为广泛的应用,其基本原理和方法在环境化学等课程的课堂教学中讲授。然而,主要用于科研的光催化氧化装置在本科实验教学过程中存在占地面积大,复套数难以提高等不足,为此研制了适用于本科实验教学的光催化氧化实验装置。研发的装置具有体积较小、造价较低、使用方便等特点,通过多届本科生实验教学的应用,获得了满意的实验效果。

Photo-catalytic oxidation technology,as an effective way to remove refractory organic compounds,is widely concerned at present.The fundamental principle and technique of it has been embodied in undergraduate experimental chemistry courses.However,there are some disadvantages of currently available photo-catalytic oxidation apparatuses and equipments for students which were copied from scientific laboratory,in order to correct the existing problems of it in undergraduate course,a novel analog experimental teaching instrument were developed.The equipment is of small,flexibility of operation,easy access and cost-effective,etc.,It gains satisfying effects after the practice of the several undergraduate teachings.
