The moisture and gas content of charcoals and the activation of charcoal for use in gas masks was the major project undertaken by the branch laboratory at Princeton University. George A. Hullet, a professor of physical chemistry at the University, directed a staff of 14 chemists who as soldiers were stationed there during the war. Fred Neher, an organic chemist, was assisted by three graduate students employed by the Bureau of Mines in the synthesis of several compounds suggested by E. Emmet Reid (27). ...

Table 9-1 lists design features of the exposure chambers in the United States that have air-cleaning equipment. The facility at the University of Maryland Hospital, Baltimore, has a chamber with activated-charcoal and high-efficiency particle filters and controlled temperature and humidity. St. Vincent s Hospital and New York University, New York City, each have a clean-room facility. The University of Pennsylvania Hospital, Philadelphia, has a self-contained, reinforced-concrete... 

The thermodynamic arrow of entropy points towards a natural tendency to disorder which tells us that the universe will expand rather than contract, that the bath water will run out of the bath, cooling as it does so, while gunpowder, when ignited, will disappear as smoke and flame. The latter can never reform as the intimate mixture of potassium nitrate, sulfur and charcoal from which it started - there being no going back or reversal during such processes. 

It is safe to say that washing with tepid water and soap, for external poisons (just cold water for the eye) and activated charcoal are the two simple and effective remedies which have the most universal benefit, according to current knowledge. 

Activated charcoal may be given as first aid if the patient presents within an hour of ingestion. Antidotal treatment is almost universally effective if administered within 6 hours of overdose. The serum paracetamol concentration measured between 4 and 16 hours determines whether antidotal treatment with acetylcysteine is required, but if a significant overdose has been taken and no result is available by 6 hours after overdose, antidote should be... 

Universal antidotes These antidotes can be given in all such conditions where nature of poison is not known or where more than one poison is suspected to be taken e.g. charcoal as adsorbent of toxins and alkaloids, tannic acid for precipitating alkaloids, glycoside and many metals. 

Charcoal. Activated coconut charcoal has gained the status as the almost universal solid sorbent. Petroleum-based charcoal is less active, but is also widely used. Charcoal is a very effective sorbent and is generally used for collection of nonpolar organic solvent vapors. It also collects polar organics, but they frequently cannot be recovered. However, many organic substances that are reactive, polar, or oxygenated (e.g., chloroprene, acetic acid, and acetone) have been successfully collected and recovered from charcoal. Substances for which charcoal tube methods have been validated are listed in Table II. 

EXPERIMENTAL The sampling and analytical method employed in determining the various solvent vapor concentrations in air are described in detail by White etal (A)and NIOSH (2), Four Bendix National Environmental Instruments Model BDX 30 Personal Samplers were used daily (one in each laboratory) with large size charcoal tubes (SKC cat no. 226-09-100) which contained two sections of activated charcoal per tube (a 400 milligram section followed by a 200 mg backup section to indicate when "breakthrough" of the main section has occurred). The sampling pumps were operated at a rate of one liter per minute and were calibrated by means of an Environmental Compliance Corporation Model 302 Universal Pump Calibrator (a device that generates a thin film of soap which is carefully timed as it traverses a very... 

Castner, Hamilton Young — (Sep. 11, 1858, Brooklyn, New York, USA - Oct. 11,1899, Saranac Lake, New York, USA) Castner studied at the Brooklyn Polytechnic Institute and at the School of Mines of Columbia University. He started as an analytical chemist, however, later he devoted himself to the design and the improvement of industrial chemical processes. He worked on the production of charcoal, and it led him to investigate the Devilles aluminum process. He discovered an efficient way to produce sodium in 1886 which made also the production of aluminum much cheaper. He could make aluminum on a substantial industrial scale at the Oldbury plant of The Aluminium Company Limited founded in England. However, - Hall and - Heroult invented their electrochemical process which could manufacture aluminum at an even lower price, and the chemical process became obsolete. Castner also started to use electricity, which became available and cheap after the invention of the dynamo by - Siemens in 1866, and elaborated the - chlor-alkali electrolysis process by using a mercury cathode. Since Karl Kellner (1851-1905) also patented an almost identical procedure, the process became known as Castner-Kellner process. Cast-...

Charcoal is produced by the incomplete combustion of plant or animal products. The major use of charcoal is for outdoor cooking. The second largest use of charcoal is in industrial applications in the form of activated charcoal. The activation process involves heating the charcoal subjecting it to steam or treating with a chemical to both remove substances that have adhered to it as well as break it down into finer particles and thus increase the surface area. Activated carbon has been used for its adsorptive properties as a universal antidote in cases of poisonings, as a filter aid agent, and in decolorization processes.

Reagents Chemical compounds for comparisons of mass spectra and GC retention times were obtained from commercial sources. Pentadecanal was synthesized as before (10). Keophytadiene and solanone were obtained from H. Burton, University of Kentucky. Reagent-grade hexane was redistilled on a Vigreaux column. Water was deionized, passed through activated charcoal and distilled. Tenax GC adsorbent (60-80 mesh) was obtained from Alltech Assoc. Inc.
