Electron affinity of Carbon is 153.9 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. X + e- → X- + energy Affinity = - ∆H

The steam activation process is usually carried out at temperatures of 750-950°C in an oxygen-depleted atmosphere. The reaction between steam and carbon is described by the equation C + H2O = H2 +CO-31 kcal. The reaction may be promoted by any of several dehydrating agents such as zinc chloride or phosphoric acid.

A packed scrubbing column should have at least a 4-foot height. Liquid flow rate through the column should be at least 100 lb/hr per 1 lb/hr of DMSO decomposed. KMnO4 usage will be about 4 lb/lb of DMSO decomposed. Manganese dioxide, MnO2, forms as a solid and must be occasionally removed from the scrubber and recirculation surge tank.

Regeneration, often referred to as reactivation, is a method of thermally processing the activated carbon to destroy the adsorbed components contained on its surface. In regeneration, the adsorbed components are almost completely removed, yielding a regenerated carbon that can again function as an adsorbent.

Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution. The CIL process is frequently used when native carbon is present in the gold ore. This native carbon will absorb the leached gold and prevent its recovery. This phenomenon is referred to commonly as "preg-robbing".

Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is the solid. Activated carbon is produced specifically so as to achieve a very big internal surface (between 500 - 1500 m 2 /g). This big internal surface makes active carbon ideal for adsorption.

Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that increase the surface area available for adsorption (which is not the same as absorption) or chemical reactions. Activation is analogous to making popcorn from dried kernels ...

A mixture of high and low molecular weight molecules should be designed for the removal of the more difficult species. pH: Most organics are less soluble and more readily adsorbed at a lower pH. As the pH increases, removal decreases. A rule of thumb is to increase the size of the carbon bed by twenty percent for every pH unit above neutral (7.0).
