Study on Cesium Adsorption/Desorption Behavior of Porous Nickel

Abstract

A simplified two-dimensional mode of is established for the performance, characteristics and transportation behavior in cesium adsorption/desorption process. Subsequently the cesium absorption/ desorption ability of porous nickel were investigated by batch experiment on the condition that the pressure is lower than 10 Pa in self-made quarz vacuum device containing porous nickel with the appropriate structural features and parameters simulated above. The experiment results indicate that about 95% of cesium can be desorbed quickly and effectively with a stable process from the porous nickel show that the simulation model and the analysis method are correct and feasible which can be used as a basis for further study. According to the detailed simulation result, model reveal the considered porous nickel could be used for feasibility of cesium adsorption/desorption, which is fully meeting the application need of both higher storage capacity and stable desorption efficiency in lower pressure ambient condition.
