The paper studies the adsorption features of ²³⁹Pu in phyllitic slate and clay media through static experiment method. The two different geo-media were collected from a site for disposing very low level waste (VLLW) as experimental samples. Experimental results have shown that an adsorption equilibrium time of ²³⁹Pu in phyllitic slate and clay is approximately 10 days, and the adsorption coefficient (K_d) B Bvalues of phyllitic slate and clay are about 6000 ml/g and 2700 ml/g, respectively. The experimental result of particle size effect indicates when adsorption of plutonium in particle samples increases, the KBdB values of these two geo-media increase while the particles decrease in size. And the experimental impact on aqueous phase pH value reveals that K_d of ²³⁹Pu in creases at higher aqueous phase pH value, illustrating stronger adsorption capacity. Experimental data are also measured through the curve fitting, KBdB values are thus obtained theoretically.
