【Abstract】 A theoretical expression, similar to the Freundlich adsorption isotherm, was proposed in a previous report to express the relationship between the degree of formation and the free ligand concentration （L） in a solution of mononuclear metal complexes. In the present investigation, this relationship has been verified for the system of uranyl thiocyanate complexes （μ=1, [H⁺]=0.1）. It was found that （?）=7.3（L）^1.006 while the ratio Y₀ of the total concentration of uranium to that of the uncomplexed uranyl ion may be calculated from the following expression: log Y₀=integral from n=0 to （L） （?） d（L）/（L）=3.1（L）^1.006 Also the average molar extinction coeficient ε_m at λ=436 mμ was found to be ε_m=350（L）^0.755更多还原
