Title Adsorption of amine functional groups modified macroporous foams radioactive wastewater
Abstract
The subject of foamed synthetic macroporous silica materials (Macroporous Ordered Silica Foam, MOSF) as a substrate carrier is designed to prepare particles having acertain morphology, pore surface containing uranyl ion selective adsorption function of thefunctional group MOSF materials for adsorption simulated radioactive wastewater uranylions or other heavy metal ions, decrease the risk of radioactive pollution and resource recovery role. This paper focuses on solving the following three questions: ① QSARadsorption performance MOSF morphology and pore structure of the material between the uranyl ion; between ② amine functional group modification method and a modifiedrate of uranyl ion removal the intrinsic relationship; ③ MOSF large pore structure of the solid-liquid mass transfer is more conducive to a two-phase interfacial reaction. By studying these issues in order to evaluate foam Ordered mesoporous silica material as the adsorption and separation matrix material compared with other porous materials in terms of advancement, to address various aspects of the nuclear fuel cycle to producenuclear science and technology and the application process harmless radioactive wastetreatment and disposal to provide theoretical and experimental basis.
