硅胶吸附放射性同位素^(131)Ba的研究

Studies on adsorption of radio isotope ^(131)Ba in silica gel

通过硅胶吸附放射性同位素131Ba,发现硅胶对131Ba的吸附率与硅胶的粒径、温度、吸附时间、和放射性同位素131Ba的浓度有关,而硅胶的脱附率与冲洗时间、冲洗液的体积、温度和不同的冲洗液有关。

By adsorbing radio isotope l31Ba in silica gel, we discovered that adsorption of silica gel is related to particle size of silica gel, temperature, time of adsorption and concentration et al, but desorption rate of silica is related to rinse time, volume of rinse solution, temperature and different rinse solution et al.
