摘要
Adsorption of basic dye methylene blue by some Indian clays has been studied. BET plotting of the adsorption isotherms was applied to determine the specific surfaces of clays and heat of adsorption. About 10-20% lower values of specific surfaces were obtained when compared with the most accurate gas-adsorption BET results and its probable reasons discussed. The calculated heat of adsorption values confirm the physical adsorption.
