Jul 20, 2018 · To investigate the sorption capacity of cesium on different forest and agricultural soils, batch sorption experiment was conducted. The Freundlich constant K reflecting the sorption capacity differed greatly with soil types (6 forest soils and 12 agricultural soils) (0.36–5.50 [(µg g−1) (µg L−1)−1/n]). The sorption capacity on agricultural soils was generally higher than that on .
