摘要： A particle diffusion coefficient measuring device is provided with a hollow-fiber including micropores on its surface. The hollow-fiber provides a passage for particle suspension to transport through. The device is also provided with a fluid passage formed outside the hollow-fiber to communicate with the hollow-fiber via the micropores. The fluid passage provides a passage for an electrolyte solution to transport through in such a manner that the electrolyte solution is delivered to flow in the same direction as that of the particle suspension and is discharged from the fluid passage. The device detects a concentration change of the particles in the electrolyte solution discharged out of the fluid passage over a time change and calculates a particle diffusion coefficient by using the concentration change of the particles over the time change.
