Methods for determining pore volume distribution with respect to size of porous materials are analyzed and it is shown that the most precise methods are those in which capillary effects do not appear. It is shown that mercury porosimetry and the method of liquid displacement by gas have considerable errors in the large pore region, which is due to a percolation effect. It is shown that determination of the pore volume distribution from air flow measurement gives too distorted results, so its use is inadvisable.
