  Various radionuclides such as Cs,Rb,Mo,Cd,Ru,Tc,and I are emitted from the off-gas stream of nuclear facilities (pyro-processing pretreatment system).To effectively trapping of radionuclides,the development of model under various key operating conditions is required.The main goal of this work is systematically to investigate the high temperature adsorption equilibrium and high temperature adsorption dynamic characteristics of gaseous radioactive nuclides [1,2].The dynamic model was formulated based on the Mineo model [3] with Langmuir isotherm.The concentration profiles for different model parameters are compared (Fig.1).
