摘要
采用家用微波炉加热再生硅胶的方法,考查了微波功率、时间及再生硅胶质量之间的关系,结果表明,微波加热干燥硅胶500g,功率为60%时,只需10分钟,颜色由粉红色变为深蓝色。比烘箱加热干燥硅胶,可节约时间和电能10倍以上,达到了快速、节能、提高工作效率的效果。目前此种方法已经在分析化学实验室实践应用。
This paper explores a method of adopting household-use microwave heating the rebirth silica gel, and ex- amines the relation between power of microwave, time and rebirth silica gel quality. The result shows that it takes only 10 minutes to dry rebirth 500g silica gel at the power of 60%, and the color changes from pink to dark blue. It can save time and electric power than the oven, and function at high speed, efficiency and power saving. At Present the method has been used in practical application in the analysis chemistry laboratory.
