高中化学实验教学中实验的绿色化实施策略

Greening Implementation Strategies in Senior High School Chemistry Experiment

近年来环境问题日渐严重,为了人类与自然环境的可持续发展,"绿色化学"势在必行。高中化学实验中对环境的保护以及绿色化处理,正是基于这种理念下提出的。高中化学实验绿色化实施的策略包括:减少试剂用量,改进药品组成;教师精密设计,促使试剂"重复使用";化学试剂的生活化;寻找可替代低污染化学试剂;实验装置的微型化改进;实验后废弃药品及实验废物处理。

Environment problem is increasingly serious in recent years. In order to implement the strategy of human and natural environment sustainable development, the environmental protection in chemistry experiment and also green processing are imminent based on the idea of ＂green chemistry＂. In this paper, the importance of green chemistry in senior high school chemistry experiment teaching was discussed, problems that should be paid attention were discussed, and strategies for green chemistry experimental teaching were pointed out as follows： reducing the consumption of reagents and improving the composition of drugs, teachers＇ precise design to promote the reuse of reagents, chemical reagents based on daily life materials, looking for alternative low pollution chemical reagents, miniaturization im- provement of experimental devices, and treatment and recycling of abandoned drugs and wastes.
