Abstract

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.

透析係數가 常數로서 나타날 수 있는 條件究明의 一環으로서 透析液 單位體積當의 透析膜面積인 比表面積과 透析膜孔의 크기가 透析에 미치는 영향을 究明하였다. 1回의 透析實驗에서 任意時間區間마다 任意부피의 透析液試料를 잇따라 菜取하는 方法(間歇試料菜取法이라 呼稱하기로 함)은 透析係數를 求하는 方法으로서 採擇할 수 있음과, 또한 透析膜孔이 상당히 크더라도 膜을 通한 擴散係數는 自由擴散係數에 미치지 못함을 밝히었다.
