Abstract
The reaction between Pu(IV) and N,N-dimethylhydroxylamine in HNO3 solu tion passes through the reversible Step (CH3)2NHOH+ + Pu4+ reversible (CH3)2NO + Pu3+ + 2H+, the irreversible step (CH3)2NO + Pu4+ --> CH3N( O)CH2 + Pu3+ + H+, and subsequent fast hydrolysis of the nitrone. The kinetic expressions of the slow reaction steps are found. The rate con stants are determined.
