Abstract
A boundary-value problem describing the process of stationary dialysis was formulated and solved. Concentration fields of alanine and phenylalanine in solutions and their constants of distribution between the solution and cat ionite membrane phases were measured by laser interferometry. The diffusion coefficients for these amino acids in the cationite membrane were calculat ed.
