Study on hydrolytic stability constant of U(IV) by titration
摘要
The hydrolysis behavior of U(IV) was preliminarily explored by experimental methods, and the hydrolysis characteristics of U(IV) were determined. The results show that the absorption characteristic peak of U(IV) hydrolyzed products is between 380 and 420 nm, the hydrolytic process is not linear and reversible, and the hydrolysis reaction of U(IV) includes multiple processes. There are 4 integer hydrolysis stability constants of U(IV) were experimentally analyzed. With the increasing of OH− concentration, the mean coordination number of OH− increases.
