摘要：
A novel method for the fast separation and purification of Mo(VI) from fission products of uranium is presented. All impurities of Mo(VI) including, lead, ytterbium, zirconium, lanthanum, cerium, ytterium, uranium, strontium, and barium ions, were fast extracted by using aminofunctionalized mesoporos molecular sieve (AMMS) modified by dicyclohexyl-18-crown-6 (DCCE) and 2-({(E)-1,2-diphenyl-2[(2-2-sulfanylphenyl)imino]ethylidene} amino)-1 -benzenethiol (SNSB). The time of extraction, pH, and flow rate, amount of modified aminofunctionalized mesoporos molecular sieve (MAMMS), break-through volume, and maximum capacity of MAMMS were investigated. The proposed method was applied to separation and purification of Mo(VI) from the impurities of fission products of uranium.
