摘要
Abstract
Under the current background of waste resource recycling utilization,people have begun to actively explore the sustainable development path of nuclear fuel recycling.The innovative application of ammonium phosphomolybdate(AMP)in the field of nuclear wastewater treatment is one of the research hotspots in the sustainable development of nuclear energy,which mainly involves the separation,purification and concentration of high heat release fission product 137Cs from radioactive.However,AMP has small crystal grains,which makes it difficult to separate from waste liquid and prone to clogging adsorption columns when used.This limits its large-scale industrial application.In recent years,with in-depth research on Cs+adsorbents,various AMP-based adsorbents have emerged,which are prepared by optimizing the synthesis route to produce larger particle sizes of AMP or by loading AMP onto suitable carriers.These innovations are expected to solve the aforementioned challenges.This article summarizes various methods for the preparation of large-size AMP,as well as the composite methods of AMP with organic carriers(polyacrylonitrile,polymethyl methacrylate,and alginate)and inorganic carriers(porous silica,metal-organic framework,magnetic materials and alumina).It reviews the research progress on the adsorption of Cs+from aqueous solutions by large-size AMP and AMP-loaded composite adsorbents in recent years.By considering the adsorption performance of each adsorbent,including adsorption capacity,distribution coefficient,acid and alkali resistance,radiation resistance,and recyclability,the unique advantages of coarse-grained AMP and various carriers are summarized,in the hope of providing a reference for the application of AMP in the efficient separation of Cs from nuclear wastewater.关键词
