物理化学趣味实验教学探索

Exploration on Interesting Experimental Teaching of Physical Chemistry

利用具体教学实例,阐述了通过课外教学过程来显著提高物理化学课程的教学效果。教师指导学生以新疆棉杆为吸附材料,研究实验条件对废水中重金属铬的吸附效果的影响。通过实验加深了学生对物理化学课程中表面现象、吸附动力学、吸附热力学、物理吸附、化学吸附等相关内容的理解。取得了较好的实验效果,达到了预期的教学目的,此教学案例可为以后相关课程的教学探索提供借鉴。

With the concrete examples of teaching,it was expounded that the extracurricular teaching process can remarkably improve the teaching effect of Physical Chemistry course. Under the guidance of the teachers,the effect of experimental conditions on the adsorption of heavy metal chromium in wastewater was studied by using cotton stalk as adsorbent. Through the experiment,the students＇ understanding of surface phenomena,adsorption kinetics,adsorption thermodynamics,physical adsorption,chemical adsorption and other related contents in Physical Chemistry course was deepened. And a better experimental result was achieved,to achieve the expected teaching purposes. This case can provide reference for the future teaching of the relevant courses.
