Abstract
WE have been carrying out sorption of polar molecules by graphitic acid, measuring the quantity sorbed in order to determine the interlamellar surface. The following experimental methods were used: (1) volumetric Brunauer–Emmett–Teller (B.E.T.); (2) gravimetric Joly balance1; (3) X-ray diffraction. The first two give a measure of the surface, the third technique gives a measure of the increase of space between the layers.
