高校化学实验项目涉及多种化学试剂,用量大,且大多有毒有害,是实验室污染、浪费的重要来源。通过对实验内容进行多方面调整,如减少试剂用量、替换有毒有害试剂、修改替换实验项目、多个实验项目串联实现试剂循环使用等,可达到减少排放,降低污染,实现实验教学内容低碳化的目的。
Various,numerous and toxic chemical reagents were used in college chemistry experiments.It was the important source of laboratory contamination and waste.The goals of reducing emissions,decreasing pollution and low-carbon teaching in experimental contents would be achieved by adjusting to the experimental contents,such as reducing dosage,replacing the toxic and hazardous reagents,modifying or replacing the projects,string and circling some experiments,etc.
