| Abstract: | The adsorption and exchangement of 137 Cs and UO 2 2 on the modified peat have been studied under static conditions. By the examination of the adsorption equilibrium times and the pH effects on the distribution coefficients, the different adsorption isotherms were found for 137 Cs and UO 2 2, i.e. the Langmuir isotherms for the former and the Freundlich isotherms for the latter. |
