摘　　要：研究了硅胶对131I的吸脱附与硅胶粒径、吸附时间、温度和溶液放射性污度及脱附和冲洗环境之间的关系.We have studied the silica gel adsorbing radio and desorption radio of 131I,and have found that temperature can accelerate the adsorption equilibrium,but have Little effect on the adsorption rate and slightly larger effect on the desorption rate.Alkaline or acidic fluid can easily lead 131I desorption from the silica gel.

关 键 词：硅胶 吸附 放射性同位素 131I
