Sci. 2021, 11,15 ofis not necessarily enough. This study talked about the fixation mechanism of Cs inside the solidification of geomaterials, especially when it comes to chemistry. 4. Conclusions According to the static adsorption test, the adsorption performance of Cs on geomaterials was studied, and the influence of a variety of aspects on the adsorption overall performance was discussed. Constructing the foundation for the additional solidification of waste containing radioactive components was examined within this function. The geomaterials have been synthesized from fly ash and slag, plus the synthesized geomaterials have been characterized by XRD, SEM, and N2 BET. The adsorption efficiency of the fly ashbased geomaterials and also the geomaterials doped with slag as adsorbents for removing Cs was evaluated. The effects in the pH, adsorbent dosage, and speak to time on Cs removal have been investigated. Furthermore, the Langmuir and Freundlich models were utilized to describe the adsorption equilibrium mathematically. From this operate, the fly ashbased geomaterials showed a maximum Cs adsorption capacity of 89.32 mg 1 and a high Computer of 31.02 mg 1 M1 for Cs. In addition, the applicability of the kinetic model for the adsorption method was also discussed. By means of this perform, it was proved to a particular extent that the fly ashbased geomaterials adsorb Cs additional efficiently and that they have considerable possible to be applied as adsorbents for removing Cs. Moreover, the immobilization of Cs in geomaterials was explored from a chemical perspective. In the viewpoint of environmental protection, fly ash is often utilised to treat nuclear waste containing radioactive nuclear waste liquid. In conclusion, fly ash basedgeomaterials may be a promising choice for the treatment and disposal of nuclearcontaminated waste.Author Contributions: Experiment, information evaluation, and writing, H.Z.; instruments of measurement, M.Z.; experiment and information evaluation, X.D.; experiment and information evaluation, S.F.; instruments of measurement and information evaluation, N.M.; supervision and writing, N.K.
