Abstract	투석계수가 상수로서 나타날 수 있는 조건구명의 일환으로서 투석액 단위체적당의 투석막면적인 비표면적과 투석막공의 크기가 투석에 미치는 영향을 구명하였다. 일회의 투석실험에서 임의시간구간마다 임의부피의 투석액시료를 잇따라 채취하는 방법(간헐시료채취법이라 호칭하기로 함)은 투석계수를 구하는 방법으로서 채택할 수 있음과, 또한 투석막공이 상당히 크더라도 막을 통한 확산계수는 자유확산계수에 미치지 못함을 밝히었다. The effects of specific surface area and pore size of dialysis membrane on the dialysis were studied. It was confirmed that the intermittent sampling method(in which any volume of dialyzing solution is sampled intermittently at every moment after any duration of the dialysis experiment) is suitable for the determination of a dialysis coefficient. It was also confirmed that the diffusion coefficient of a electrolyte through membrane is smaller than the free diffusion coefficient though the pore size of dialysis membrane is extremely large.
