Permeation of Copper Ion and Sodium Ion Through a Artificial Chitosan Membrane
이치영
Abstract
The permeation of cations such as sodium ion and copper ion through a chitosan membrane was investigated as part of a series of studies on pharmaceutical application and filtration of water by chitosan.
Over a 70 hour period, wth 0.02cm thick membrane, concentriation equilibrium was reached by sodium, while the copper concentration in the distilled water remained below detection limits.
The membrane constant of the chitosan membrane was calculated from the permeability constant 3.52×10^(-7)㎠/s and from the diffusion coefficient 7.95×10^(-6)㎠/s, and it was obtained for sodium chloride.
The partition coefficient of chitosan membrane was found to be 0.0443, which is close to the reported value for cellulose membrane.
Assuming that the permeation sodium ion through a chitosan membrane process on the basis of diffusion through pores, and also that sodium chloride has no special interaction with chitosan membrane, while cupric ion did not pass through.
