本文用阳离子交换树脂静态法测定了弱酸介质中UO22+和L-酒石酸络合物的稳定常數。结果是:离子强度(μ)为0.5,温度在25°、35°、45°、55℃时,β1分别为2.4×10-6、1.7×10-6、9.1×10-7、5.9×10-7;在45°、55℃时,β2分别为4.7×10-9、7.2×10-9;并求得△H(β1)=-3.8×104焦·摩-1。
Abstract：It has been determined the complex constants of Uranyl-L-tartaric acil in weak acidic media by static ionic exchange method. The results show thatihe complex compound are UO2HL-and UO2HL (H2L)3-at higher temperatures.At a constant ionic strength (u= 0.5) , β1, equals 2.4×106, 1.7×10-6, 9.1×10-7 and 5.9×107 at 25, 35, 45and55C,and β2 equais 4.7×10-6 and 7 . 2×10-8 at 45 and 55C respectively, from whioh ΔHβ) ia found to be-3.8×10 J/moI.
