Cation-exchange equilibrium and mass balance in the lichenUmbilicaria muhlenbergii

摘要

Equilibrium studies on the thallus ofU. muhlenbergii(Ach.) Tuck. confirmed that the mass balance of the exchange of Ni2+for Sr2+, Sr2+for Tl+, and Sr2+for H+was consistent with a cation-exchange mechanism of metal-ion uptake.
