Abstract
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 characteristics of the resin are negatively affected by alkaline earth meal ions. In the dynamic regime, the operation life of the resorcinol–formaldehyde resin exceeds 700 bed volumes with more than 95% efficiency of cesium sorption. More than 95% of 137Cs is eluted with a 1–3 M HNO3 solution. The eluate volume does not exceed 10 bed volumes.
