Prediction method for adsorption capacities of commercial activated carbons in removal of organic vapors
Adsorption isotherms for vapors of 13 organic solvents on 7 commercial granular activated carbons were studied. The isotherms were analyzed by the Dubinin-Polanyi equation, and relationships betwen the parameters of the Dubinin-Polanyi equation, W/sub o/ and k/sub s/, and properties of the activated carbons were investigated. It was found that W/sub o/ was approximately equal to 0.055 mL plus the micropore volume, v/sub 3.2/ (smaller than 3.2 nm in diameter), and k/sub s/ of benzene could be approximated to 2.8 X 10/sup -9/ mol/sup 2//J/sup 2/ for various types of commercial activated carbons. From the above results, a prediction method for adsorption capacities of organic vapors on commercial activated carbons was introduced, and the method was confirmed for various conditions.
