A new method for the investigation of porous structures using mercury porosimetry

摘要: Abstract The influence of wetting angle hysteresis on volume and retention mercury in porous solids was considered. Although different explanations are possible (as explained the paper), resulting effect for cylindrical pores examined sample active carbon that advancing θ A = 162°, effective value receding R 90°. rise (V m ) intruded second run after preceding reduction pressure (p) to zero corresponds with a formation spherical caps at orifice pores. dependence V p such case has been called local it used evaluate true , number radius corresponding intrusion their mean length.
