Cerium, cobalt and cesium and their isotopes were taken up inside Potamogeton crispus . The rate of uptake was subjected to environmental parameters such as pH, temperature, and interference by certain ions. Accumulation of cerium and cobalt inside 1 g of Potamogeton reached a quantity of 12 mg of Ce (III) and 3‐6 mg of Co (II). Also I g of Potamogeton can accumulate 12 KBq, 17 KBq and 20 KBq of Ce 144 , Co 60 and Cs 137 respectively. Rates of ion uptake by Potamogeton were increased by increasing pH and temperature and decreased in the presence of chemical additives. Potamogeton could be used to treat low level liquid radioactive waste.
