【摘要】 本文用色谱保留值来测定固体的比表面积。结果表明,这种方法的操作简便,设备简单,与ST-03比表面测定仪所得的结果比较偏差约±5％,是一种便于推广的常规测定方法。并用此法得出了新近开发出的腾冲硅藻土的比表面、吸附等温线,进而求出了腾冲硅藻土的微孔孔径分布曲线。更多还原

【Abstract】 By using the retention value of chromatogram, a measurement is made in this article on specific surface area of some solids. The result inditcates that this is a method of conventional measurement easy to popularize. By this method, the specific surface area and pore-size distribution of diatomaceous earth in Tengchong County is found.更多还原
