本文报导了一种测定固体比表面积的简易方法.即采用干燥器等简易设备,以乙醇蒸气作为吸附质进行静态的吸附的方法,其测定结果与气相色谱法测定结果比较,相对误差不超过5%.
In this paper, a simple method for the determination of specific surface area of solid is reported, which is a simple method using a simple device such as a dryer to adsorb ethanol vapor as adsorbate. The relative error between the determination results and gas chromatography results is less than 5 %.
