International Journal of Chemical Engineering, Volume 2026, Issue 1, 2026.Sorption is a well‐known method for radionuclide removal, but the high cost of synthetic sorbents constrains its application. This study investigates the potential of locally sourced diatomite from Kariandusi, Kenya, as a cost‐effective sorbent for capturing barium (Ba), cobalt (Co) and zinc (Zn) from radioactive liquid waste.
