The decontamination and volume reduction of Cs contaminated soil by efficient Cs removal remains a
great challenge after the Fukushima Daiichi Nuclear Power Station accident. In present work, we studied the removal
of Cs from the clay soils by treating with hydrothermal cations in a column system. The new results showed that Cs
could be selectively removed from its collapsed interlayers in vermiculite by hydrothermally heating at 150°C.
