Description

Interaction of uranyl ion with orthosilicic acid and polymeric silicic acids is investigated using spectrophotometry. Equilibrium constant of UO22+ + Si(OH)4 = UO2OSi(OH)3+ + H+ reaction is lg K=-2.56±0.09 in solutions with ionic strength I=0.1-0.2. Stability constant of UO2OSi(OH)3+ complex is determined

Abstract (Russian)

Спектрофотометрическим методом изучено взаимодействие иона уранила с ортокремниевой кислотой и полимерными кремниевыми кислотами. Константа равновесия реакции UO22+ + Si(OH)4 = UO2OSi(OH)3+ + H+ найдена равной lg K=-2.56±0.09 в растворах с ионной силой I=0.1-0.2. Константа устойчивости комплекса UO2OSi(OH)3+ определена
