本文改进求取对应溶液的方法,并在氧铀离子与硫氰酸根的络合体系的研究中验证报告Ⅰ中提出的关系式,并得到这一体系在离子强度μ=1(NaClO4),酸性(H+)=0.1M时的平均络合数,络合度对数和平均克分子消光系数εM(λ=436毫微米)可用下式表示
n=7.3(L)1.006,logY0=3.1(L)1.006M=350(L)0.755

A theoretical expression,similar to the Freundlich adsorption isotherm,was proposed in a previous reportsup>[1] to express the relationship between the degree of formation n 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).
