DETERMINATION OF M.B. VALUE OF ACTIVATED CARBON REAGENT:
Methylene Blue Solution – Dissolve 0.15 gram of methylene blue confirming to IS: 2230-1962 in 100 ml of Distilled Water (Distilled water having pH value 7.0). PROCEDURE : Weigh accurately about 0.1 gram of the material, as received, with accuracy of 0.01 gram and transfer to 50 ML Glass stoppered flask. Add from a burette 10 ml of methylene blue solution and shake for 5 minutes. After the first 10 ml are decolorized continue to add methylene blue solution (1 ml at a time) till the blue colour disappears for 5 minutes. Decolorizing power of Activated Carbon is expressed in terms of milligrams of methylene blue adsorbed by 1 gram of activated carbon. (This value is MB value).
CALCULATION :
DECOLOURIZING POWER = 15 x V Divided by 10 x M
Where V = volume in ml of methylene blue solution consumed, and M = mass in gram of the material taken for the test. (Use methylene blue of any standard company to prepare solution and compare solution with standard solution of methylene blue as it does vary batch to batch).

Activated carbon is useful in drinking water treatment because it acts as an adsorbent , and can effectively remove particles and organics from water. These organics are of great concern in water treatment because they react with many disinfectants, especially chlorine.
The use of granular Activated Carbon in wastewater treatment systems is a proven process for removal of organic compounds. As a tertiary treatment method, carbon adsorption and regeneration have been used to process domestic wastewaters contaminated with industrial wastes of organic origin as well as biologically treated waste waters. Activated Carbon, when contacted with water containing organic material, will remove these compounds selectively by a combination of adsorption of the less polar molecules, filtration of the larger particles, and partial deposition of colloidal material on the exterior surface. The quantity of Activated Carbon required will depend upon the degree of contamination.

An amorphous from of carbon characterized by high adsorptivity for many gases, vapors, and collodial solids.
Used for water and air purification, solvent recovery, waste treatment, removal of sulfur oxide from stack gases and "clean'' rooms as deodorant, and for air conditioning.
