摘要：

介绍了一个实验室废液回收及效果评价的实验。进一步巩固学生对晶体制备、化学分析、仪器分析等基本操作的掌握，同时让学生体验废液处理过程中可能出现的一系列条件选择及控制的问题，提升学生分析问题、解决问题的能力，在不断探索中提升学生的学习兴趣，同时能强化学生的人文教育。

关键词: 废液回收, 基本操作, 提升兴趣, 人文教育

Abstract:

This paper introduces an experiment about waste liquid recovery and effect evaluation in laboratory. Through this experiment, the basic operations of crystal preparation, chemical analysis and instrumental analysis are further consolidated. At the same time, it allows students to experience a series of possible problems of condition selection and control in the process of waste liquid treatment. We hope to improve the students' ability to analyze and solve problems, enhance their interest in learning, and strengthen their humanistic education.

Key words: Waste liquid recovery, Basic operation, Enhance interest, Humanistic education
