Zusammenfassung:The invention belongs to the technical field of radioactive waste treatment, and particularly relates to hydrophobic silver-loaded zeolite as well as a preparation method and application thereof. The prepared hydrophobic silver-loaded zeolite has the advantages of high hydrophobicity, stable adsorption capacity in a high-temperature water vapor environment, radiation resistance and the like. The hydrophobic silver-loaded zeolite prepared by the invention can maintain the hydrophobicity and adsorbability in a high-temperature and high-humidity irradiation environment when a containment vessel has an accident. When the prepared hydrophobic silver-loaded zeolite is used for adsorbing methyl iodide radioactive waste, the adsorption efficiency of high-temperature and high-humidity methyl iodide gas is 80% or above, the contact angle of the zeolite in the irradiation environment is reduced by 10%-40%, radioactive iodine steam can be adsorbed in the irradiation environment, the adsorption efficiency is 60% or above,
