【摘要】 采用流动色谱法,在液氮温度下测定不同原料来源和不同外型的几种活性炭的吸附等温线。用一点法、B.E.T三参数法,层厚法,孔模型法计算其比表面。采用圆筒孔等效模型计算孔径分布。研究结果表明:几种活性炭均系比表面大（>1000m²/g）和微孔发达的物质。根据D-R方程计算微孔体积V₀和特征吸附能E等。更多还原

【Abstract】 This paper concerns the measurement of adsorption isotherm of several kinds of activated carbon made from different raw materials and of different shape. The measurement was done by means of flow chromatography at the temperature of liquid nitrogen. One point method, B. E. T. three parameters method, layer thickness method and pore model method were used to obtain the specific surface area. The pore size distribution was obtained by using cylinder pore equivalent mcdel calculation. The results indicated that all the activated carbon studied had large specific area（>1000m²/g）and were micropore-rich materials. Micropore volume V₀ and characteristic adsorption energy were calculated with the aid of D-R equation.更多还原
