In this paper,the adsorption behavior of quadrivalent,pentravalent and hexavalent neptunium on silica gel in nitric acid solutions was investigated by batch experiment.

本文研究批式实验条件下，硝酸溶液中Np、 Np和Np在硅胶上的吸附行为。

The adsorption isotherm of neptunium on silica gel correspond to the form of Langmuir isotherm. According to Clausius-Claperon equation,from the slope in InKd vs 1/T plot,adsorption heat could be estimated. From the data of adsorption heat it is concluded that the adsorption of neptunium on silica gel in nitric acid solutions belongs to chemical adsorption and the adsorption process is an endothermic reaction.
