Investigation of strontium sorption onto Kula volcanics using Central Composite Design

► We model strontium sorption on non-treated and HCl-treated Kula volcanics to obtain data on the radionuclide migration. ► Central Composite Design was used in the experiments avoiding the traditional “one-factor-at-a-time” experiments. ► The results show that the Kd values are higher at pH 7-9 which is the pH range of the natural waters.
