    Notes: Abstract The adsorption-exchange equilibrium time and the adsorption isotherms of UO2 2+,137Cs,169Yb and HPO4 2− on modified peat have been investigated by batch experiments. The effect of pH on the adsorption-exchange percentage (E) and the distribution coefficients (K d) was also examined. It was found that the adsorption-exchange of UO2 2+ and169Yb on the modified peat was described well by Freundlich isotherm, whereas the adsorption-exchange of137Cs and HPO4 2− on modified peat corresponded to a Langmuir isotherm and the maximum adsorption capacities of the modified peat for137Cs and HPO4 2− ions were 4.4 and 4.1 μg/g respectively. The optimum pH for the adsorption-exchange of UO2 2+,137Cs,169Yb and HPO4 2− on the modified peat was 7.0 at 25°C.
