P区非金属性质实验的绿色化研究

Study of Green Experiment in the Properties Experiment of P-area Nonmetallic Compound

在绿色化学思想的指导下，对P区非金属化合物性质实验开展了微型化及末端绿色化的研究。实验结果表明，在不影响实验现象的前提下，可稀释某些试剂浓度至原来的1/10，降低试剂用量至常规实验的1/2～1/20，进而节约实验成本，提高实验效率；同时，通过在试管末端增加浸渍有NaOH溶液的脱脂棉来吸收处理氯气、硫化氢等有毒气体，减少了对环境的污染，大大改善实验的环境。

According to the green chemistry idea, we carried out the study of microscale method and green experimental end in the properties experiment of P-area nonmetallic compound. The results showed that the concentration of regents were diluted to 0.1 times, and the amount of the regents could be reduced to about 1/2~1/20 of the normal amount. Meanwhile, at the end of experiment, hydrogen sulfide and chlorine were absorbed through the absorbent cotton dipped with sodium hydroxide solution. These changes will result in the improving of the laboratory environment, increasing the experimental efficiency, saving the experimental expenditure and relief of the pollution of environment.
