Characteristics of water and ion exchange of Elodea nuttallii cells at high concentrations of lanthanides.

Changes of diffusive permeability of membranes of Elodea nuttallii cells following a short-term (60 min) treatment with high concentrations of lanthanides were recorded by the H NMR-diffusometry and conductometry methods. The 1-h infiltration of segments of Elodea nuttallii internodes in 10 mM solutions of nitrates of La, Nd and Lu resulted in the increased leakage of electrolytes from cells, but has no effect on a water diffusive permeability of membranes. In samples subjected to a 30 min pretreatment with a water channel inhibitor HgCl the water diffusive permeability of membranes (P) drops down under the influence of lanthanides, as well as an outcome of electrolytes.
