A membrane technique was adopted to determine experimentally the value of the molecular diffusivity of carbon dioxide in a CMC solution which was pseudoplastic in its flow behavior. Molecular diffusivities of carbon dioxide in water, glycerine and sucrose solutions were also determined with the same technique to check its reliability.The measured value in water agreed favorably with other workers' results. As is well known the viscosity of the Newtonian liquids used was confirmed to affect appreciably the value of the molecular diffusivity of carbon dioxide. However, it was found that the pseudoplastic viscosity of the CMC solution did not exert a marked effect on the value of molecular diffusivity of carbon dioxide; this fact may be ascribed to the difference, if any, in the structural pattern between the CMC solution and the Newtonian liquids. Additional studies regarding this point remain to be conducted.
