Chlorine Story American Chemistry

Chlorine chemistry is also used to produce 93 percent of all prescription drugs used in the U.S. Some people are surprised to learn that chlorine works for the environment, too. Chlorine is an important component in the development and manufacture of materials that make vehicles lighter—thereby increasing gasoline mileage.

Coadsorption of gold with chlorine on CeO 2 (111)

Abstract. To investigate the effects of chlorine on the Au/ceria catalysts, the adsorption of gold or chlorine and their coadsorpiton on the stoichiometric and partially reduced CeO 2 (111) surfaces are studied from the first principles. It is found that the adsorption of Au is significantly enhanced by the chlorine preadsorption on the stoichiometric CeO 2 (111) surface; while on the

Extraction of Gold

When the gold has solidified, the molten silver chloride collected on the surface is run off, carrying with it a small proportion of gold. When silver is the chief impurity in the gold, as in that found in Australia, the process is specially applicable. The gold has a degree of purity of 99.1 to 99.7 per cent.
