This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 edition. Excerpt: ... B. Firth, Zeits. physikal. Chem. 86, 294 (1913). H. Baerwald6 showed that by heating charcoal to over 500 deg. C, its adsorptive power is increased considerably; also that charcoal from coconut shell is a much better adsorbent than that from the soft part of the nut, or from wood. The adsorption of nitrogen, oxygen, and air on coconut shell charcoal at about IS deg. C. has been measured by F. Bergter.7 Fig. 54. Adsorption of Gases on Charcoal at Low Pictures (Claude) The measurements at low pressures (1-10 mm. mercury) show that at the same pressure oxygen is adsorbed in about 30 or 40 times as great an amount as nitrogen, while the adsorbing power of air is about 3 times that of nitrogen. At low pressures the amount adsorbed is proportional to the final pressure. It was also observed that in the case of nitrogen, about 96 per cent of the total amount is adsorbed almost instantaneously, while the rest is adsorbed very slowly. In the following tables and curves of results obtained by different investigators, the pressure is given in mm. of mercury, the volume adsorbed, in cm.3 (measured at 0 deg. C. and 760 Ann. Phys. S, 84 (1907). 7 Ann. Phys. S7, 472 (1912).
