Abstract
It is the best honor in my life as a researcher of membrane science to be accorded the 1995 young investigator's award by the Membrane Society of Japan. I would like to thank the president, Professor Takeo Shimizu and the persons concerning the award for their help.The present review is based on the results of the investigation supervised by Professor Kiyotaka Sakai of Waseda University in his laboratory for about fouryears. I am also sincerely indebted to him and my collaborators.A new method of determining solute permeability of a hollow-fiber dialysis membrane from absorbancy of a solution in the narrow lumen of the membrane using quartz optical fibers has been developed. Solute permeability of a single hollow-fiber membrane without the influence of convective solute flux was obtainable through the method.Mass transfer coefficient around a single hollow-fiber membrane in ideal laminar flow was also determined by the method. Analogy between mass transfer and heat transfer in annular laminar flow was experimentally confirmed using the method.
