Wet/dry flow method

It was found that the mean pore sizes of the membranes determined from the wet/dry flow method were more than 2.7% lower than those determined by means of the gas permeation test (Khayet et al., 2004a). Martinez et al. (2002,2003), by using a similar wet/dry flow method, obtained pore size distributions of various porous hydrophobic membranes (TF200, TF450, TFIOO, GVHP, and HVHP) with mean pore sizes larger than those...
