The solvent extracts can be cleaned up by traditional column chromatography or by solid-phase extraction cartridges. This is a common cleanup method that is widely used in biological, clinical, and environmental sample preparation. More details are presented in Chapter 2. Some examples include the cleanup of pesticide residues and chlorinated hydrocarbons, the separation of nitrogen compounds from hydrocarbons, the separation of aromatic compounds from an aliphatic-aromatic mixture, and similar applications for use with fats, oils, and waxes. This approach provides efficient cleanup of steroids, esters, ketones, glycerides, alkaloids, and carbohydrates as well. Cations, anions, metals, and inorganic compounds are also candidates for this method [7],...

In addition to faucet units for water treatment, activated carbon filters are used with water jugs and in portable water treatment systems for use in remote areas. Of the home water treatment units, there are point-of-entry units that are placed in line and treat water supplies to whole households and commercial buildings. Both point-of-use and point-of-entry filters often contain a combination of activated carbon for the removal of organics and Cryptosporidium and ion exchange resins for the removal of metals and inorganic compounds. 

Activated carbons of high absorptivity show high ability to remove organic pollutants. Carbons give good effects in removal of refractional compounds (resistant to conventional methods). It was stated, that carbons may adsorb metals and inorganic compounds such as antimony, arsenic, bismuth, chromium, cobalt, fluorine, chlorine as well as viruses resistant to chlorination [11—14]. 

It is now well established (2-4) that the oxidation of carbon can be catalysed by certain metals and inorganic compounds although information is less comprehensive for water vapour. As a consequence the effectiveness of a number of elements in promoting the oxidation of the radiant heater tube coke in this environment has been surveyed. 

While Eq. 9.4-13 will generally be used to calculate the fugacity of a species in a solid mixture, especially involving organic compounds, there are cases of true solid mixtures, especially involving metals and inorganic compounds. While vve defer considerations of such mixtures until Sec. 12.4, it is useful to note that the activity coefficient for a species in a true solid mixture, following Eq. 9.3-11, can be written as... 

Tin, metal, and inorganic compounds Dusts irritating to the eyes, nose, throat, and skin. Proionged inhaiation may cause chest x-ray abnormalities. Some compounds react with water to fomn acids (tin tetrachloride, stannous chloride, and stannous sulfate) or bases (sodium and potassium stannate). 2mg/m (as Sn) 100 mg/m (as Sn) Metallic tin is odorless with a dull, silvery color.
