Abstract

Application of two inorganic hexacyanoferrate sorbents (T-35 and NPF-HTD) for radiochemical analysis of 137Cs in various water samples was studied. The results of batch experiment for cesium sorption revealed that both sorbents are suitable for preconcentration of cesium at the pH range of 0.5–11. Column experiments revealed that the NPF-HTD sorbent provided significantly better cesium sorption than the T-35 sorbent due to better sorption kinetics. The sorbents were tested using 1 L of raw and acidified fresh water and seawater as well as 7.2 L water sample from Techa River (activity of 1.36 ± 0.21 Bq L−1 was found). 1.5 g of the NPF-HTD allowed for cesium recovery of 86–98.7% depending on type of water sample.
