保护环境是可持续发展的重要保证,是建设生态文明的基本要求。作为化学教育工作者,更应率先垂范,以高度的社会责任心和使命感投入改进实验方法、创建绿色化学实验中来,并让环保意识成为我们日常生活、工作的行为准则。氯气是一种有毒气体,是高一化学的重要实验教学内容。如果实验方法不当,则很容易污染环境,损伤人的喉黏膜和肺,严重时可使 Protecting the environment is an important guarantee for sustainable development and a basic requirement for building an ecological civilization. As a chemical education worker, we should take the lead in setting examples and devote a high sense of social responsibility and mission into improving experimental methods, creating green chemistry experiments and making environmental awareness our daily life and work code of conduct. Chlorine gas is a poisonous gas and is an important experimental teaching content of chemistry. If the experimental method is inappropriate, it is easy to pollute the environment, damage the human laryngeal mucosa and lungs, severe cases can make
