Adsorption material with cesium adsorption and solidification functions and preparation method

The invention discloses an adsorption material with cesium adsorption and solidification functions. A process for preparing the adsorption material comprises the following steps: preparing a substance G from FeCl3.6H2O, FeCl2.4H2O, NH3.H2O and ethanol; after the substance G reacts with ammonia water and ethyl orthosilicate, carrying out magnetic separation by adopting a magnet; removing supernatant and adding de-ionized water to obtain a solution O; preparing a mixture T from bentonite, tetrasodium pyrophosphate and NaCl; centrifuging supernatant and adding the de-ionized water to obtain a solution U; dropping the solution O into the solution U; drying the obtained solution V for 6 hours to obtain a substance W; enabling the substance W and phosphoric acid to react to obtain a mixture Z; and drying the mixture Z for 6 hours to obtain a substance, namely the adsorption material with the cesium adsorption and solidification functions. The adsorption material with the cesium adsorption and solidification functio
