| Popis: | The behaviour of isotope tracers in diffusion processes was investigated. In systems of organic binary solutions gradients of chemical concentration were present. Using the capillary method the tracer and the mutual diffusion coefficients were determined. It was found that the tracer diffusion coefficient is equal to the mutual one if the tracer moves in the same directions as the unlabelled part of component and the ratio of both parts of component is time independent. When both conditions are not justified the tracer diffusion is due to the simultaneously mutual and self-diffusion processes. |
