초록 The composite charged mosaic membrane (CMM) endurable to mechanical pressure in practical application was investigated from the same aspect of solute and solvent transport as cross coefficients and estimated by taking account of active charged mosaic membrane without reinforcement. The reflection coefficient indicated the negative value that suggests preferential material transport and is independent of active charged group. The transport properties were also supported by the membrane potential measurement.

Membrane system I:(0.1~0.0001mole/dm3)-CaCl2 soln. II CMM II water

Membrane systemII:(0.1~0.0001mole/dm3)-CaCl2 + Sacchrose II CMM II CaCl2 soln.

The system apparatus were same as above. The volume change vb. time in system I used sacchrose as impermeable solute indicated the linear. The salts concentration change vs.time in system II. The experiment results on the CMM were reproduced by using the results of the supported membrane and the estimated active CMM thickness. In addition, there was on difference between both membranes with respect to the reflection coefficients and membrane potential and we are estimated more selective transport magnesium salt then calcium salt across CMM.
