中学化学实验直接反映化学与环境的关系,是进行绿色化学教育的前沿阵地.因此,绿色化学实验是新课程反复强调的一项重要内容.然而,目前中学化学实验存在两大问题:一方面,尽管教材中的一些实验已经考虑了环保因素,但从绿色化学这个角度看,教材中许多实验设计还存在明显不足;另一方面,目前中学开设的学生分组实验次数多,实验产生的“三废”量很大,成分复杂,浓度较高.而目前多数 Chemistry experiments in middle schools directly reflect the relationship between chemistry and the environment, is the front line for green chemistry education Therefore, the green chemistry experiment is an important part of the new curriculum repeatedly emphasized.However, there are two problems in the chemistry experiment in middle schools: on the one hand, Although some experiments in the textbook have taken environmental factors into account, from the perspective of green chemistry, there are still many deficiencies in the experimental design of textbooks. On the other hand, there are a large number of experimental groups of students in secondary schools and three wastes "Large amount, complex composition, high concentration, while the current majority
