从国家环保政策省思中学化学实验中四氯化碳的使用

Reflection on the Use of Carbon Tetrachloride in Middle School Chemistry Experiments based on National Environmental Protection Policy

根据国家针对四氯化碳的环保政策,思考中学化学实验中四氯化碳的使用问题。分析人教版高中化学教科书中使用四氯化碳的化学实验和四氯化碳的用量,提出寻找替代试剂、循环使用试剂、分离处理废液、减少其他实验这4个实验室控制四氯化碳使用的措施。

This paper discussed the use of carbon tetrachloride in middle school chemistry ex- periments according to the national environmental protection policies for carbon tetrachloride, an- alyzed the chemical experiments using carbon tetrachloride and the amount of carbon tetrachloride in chemistry textbook for senior high school. Put forward four measures for controlling the use of carbon tetrachloride, finding alternative reagents, recycling reagents, separation and disposal of waste liquid, and reducing unnecessary experiments.
