Özet

The migration behavior of Cs-137 extracted from the contaminated tea at Chernobyl accident in sandy clap soil has been studied by batch and column experiments. Time dependent sorption behavior of Cs-137 extracted from the tea reaches equilibrium slower by 6.5 times than Cs-137(+) ions. However, the distribution coefficient of Cs-137 extracted from the tea for the sandy clay soil was higher than that of Cs-137(+) ions. These results indicate that the sorption of the Cs-137 attached to the organic materials dissolved from the tea on the sandy clay soil is slower than that of Cs-137(+) ions, and the Cs-137 attached to the organic materials have more affinity to the sandy clay soil than Cs-137(+) ions.
