Determination of methylene blue adsorption value
Use a known concentration of methylene blue solution, adsorb it onto activated carbon, and then measure it using a spectrophotometer. Methylene blue can characterize the number of pores in activated carbon and is an important indicator for liquid-phase adsorption of activated carbon.
