| Abstract: | Nondisintegrated sprayed dried cells of Scenedesmus obliquus have been applied for the study of the cumulation of metal cations. It has been found that algal cell walls behave predominantely as polyfunctional weakly acidic cation exchangers. Equilibrium constants for different exchange reactions have been determined radiometrically which allow to calculate the form of algal cell walls in various experimental conditions. Metal cations present in microconcentrations may be cumulated predominantly by another cell wall ligands in comparison with the cumulation of macroconcentrations of the same cations. |
