基于环保理念的物化实验项目综合设计

Comprehensive Design of a Physical Chemistry Experiment Project Based on Environmental Protection

近年来,高校实验室废液排放问题备受关注,各高校出台了相关的管理措施。该文结合示范中心物理化学实验项目的开设,设计了一个基于环保理念的本科综合实验项目——实验室废液中五水硫酸铜的回收及热分析。通过此综合实验项目的教学,不仅回收了五水硫酸铜,而且可以使学生巩固已有无机化学知识(沉淀、洗涤、固液分离、浓缩结晶)和分析化学的相关知识,掌握新的理论知识(热重分析谱图的认识),提高操作技能,培养环保意识,锻炼学生分析问题,解决问题的能力。同时,该实验的综合设计也可作为思政教育素材,宣传国家的生态文明建设。

In recent years, the discharge of waste liquid in laboratories in universities and colleges has attracted much attention.Universities and colleges have issued relevant management measures. According to the Physical Chemistry Experiment Project of the Demonstration Center, a comprehensive undergraduate experiment project is designed based on the concept of environmental protection-recovery and thermogravimetric analysis of copper sulfate pentahydrate in laboratory waste liquid. Through the teaching of this comprehensive experiment project, copper sulfate pentahydrate can be recycled and students can consolidate their existing knowledge of inorganic chemistry(precipitation, washing, solid-liquid separation, concentrated crystallization) and analytical chemistry, and master knowledge of the new theory(the understanding of thermogravimetric analysis spectrum). The project can improve students’ operational skills, cultivate students’ awareness of environmental protection, exercise students’ ability to analyze and solve problems. At the same time, the comprehensive design of the experiment can be used as a material of ideological and political education to publicize the construction of national ecological civilization.
