The formation and stability of UO2(2+)-acetate complexes was studied potentiometrically, at T = 25 degrees C, at different ionic strength, 0 < I < or = 1 mol dm(-3), in aqueous NaCl solutions. Computer analysis allowed us to find the species UO2(ac)+, UO2(ac)2(0), UO2(ac)3- and UO2(ac)3(OH)2-. The dependence on ionic strength of formation constants was taken into account by using both a simple Debye-Hückel type equation and the SIT (Specific ion Interaction Theory) approach. A critical examination of the present results is given together with a comprehensive analysis of literature data.
在25℃、不同离子强度（0＜I≤1mol dm⁻³）的NaCl水溶液中，采用电位滴定法研究了UO₂²⁺ - 乙酸盐配合物的形成和稳定性。通过计算机分析，我们确定了UO₂(ac)⁺、UO₂(ac)₂⁰、UO₂(ac)₃⁻和UO₂(ac)₃(OH)₂⁻等物种。利用简单的德拜 - 休克尔型方程和特定离子相互作用理论（SIT）方法，考虑了形成常数对离子强度的依赖性。对当前结果进行了批判性审视，并对文献数据进行了全面分析。
