Abstract

The most popular method for the calculation of specific surface area is its determination from water vapour sorption isotherms. The study presented here has been designed for the purpose of optimisation and selection of the conditions of drying so as to allow the determination of specific surface area from plotted curves of the drying process. The results indicate that drying curves can be used as the basis for the determination of specific surface area, the values of which do not differ statistically significantly (α = 0.05) from those determined from isotherms of water vapour sorption (adsorption/desorption).

摘要

最常用的比表面积计算方法是通过水蒸气吸附等温线来确定。本研究旨在优化和选择干燥条件，以便能够从干燥过程的绘制曲线来确定比表面积。结果表明，干燥曲线可作为比表面积测定的基础，其值与通过水蒸气吸附等温线（吸附/解吸）确定的值在统计学上没有显著差异（α=0.05）。
