WebThe BJH method is a procedure for calculating pore volumes and pore size distributions from experimental isotherms, using the Kelvin equation. It applies only to the mesopore and small macropore size range. The Kelvin equation provides a correlation between pore diameter and pore condensation pressure.
WebHalenda (BJH) adsorption cumulative pore volume fell to 38.4% of the original by the fourth. After four cycles, the average pore diameter fell to 82% of the original. AFM tests showed that the pore structure in fibre expressed high self-similarity in statistics, and the pore structure in the fibre could be regarded as a fractal. WebSampel B = surface area 590 m2/gr, total pore volume = 1.966 cc/gr, r pore BJH= 32,6 Angstrong the surface are fixed, but the volume and size of pore increased.
