摘要：

The sorption of the basic amino acid histidine by FumasepA (R) FTCM membranes in different ionic forms is investigated over a wide range of solution concentrations. It is established that sorption limited by the stage of external diffusion. The time required for equilibrium to be established in the membrane-amino acid solution system is found to grow from 4 to 9 h when the initial concentration of the solution is reduced. The reversibility of histidine sorption is demonstrated, and the conditions of effective desorption are determined.
