High selectivity and ion-exchange character of birnessite-type sorbents make these materials promising for Sr-90 removal from radioactive wastes containing seawater. However, it is still debatable how their functional properties are related to the na

Sorption of 137Cs from seawater onto a selective cation exchanger based on resorcinol–formaldehyde resin was studied. The maximal distribution coefficient of 137Cs at the ratio S: L = 1: 1000 is (4.1–4.5) × 103 cm3 g–1. The sorption-selective
