Application in Chemical and Pharmaceutical Industries

Several factors, such as the pH of the solution, the nature of the solvent used, and the nature of the carbon surface determine the effectiveness of the decolorization process. The ash content of the active carbon that determines the amount of minerals present in a carbon is also an important factor in the use of active carbons for the purification of organic solutions because these minerals can contaminate the product being purified. Cases have been found where the active carbons can initiate catalytic 

This accurate dosing of activated carbon in the purifying solutions is particularly important in the pharmaceutical industry. The purification and decolorization of compounds such as glycerol, lactic acid and its salts, betaine, glutomic acid, and tatartic acid and their salts are generally carried out using activated carbons. 

Under certain circumstances, the undesirable components from the products can be removed by adding active carbon to the reactants. An example is the production of esthetic plasticizers. During their preparation, highly resinous substances are formed by side reactions, and these impart a dark color to the products, which is difficult to remove. By adding active carbon, the coloring matter is adsorbed immediately as it is formed and a pure product is obtained. 

The high selectivity of carbons for gold and silver in the presence of large concentrations of base metals such as copper, iron, nickel, cobalt, and antimony and their availability in abundance, in several different grades having different surface characteristics and at competitive prices, is going to play a significant future role in the
