Methylene Blue Adsorption of Activated Carbon
Methylene blue adsorption of activated carbon: it can be an indicator of the adsorption capacity for large molecules having similar dimensions to methylene blue. It is a quick test for medicinal and other carbons prepared to adsorb large molecules. The methylene blue value is defined as the number of milliliters standard methylene blue solution decolorized by 0.1g of activated carbon (dry basis).
