Description
The O2- reactions in aerated solutions, containing 1x10-4 mole/l Np(6) or Np(7) at pH 9.2-13.7 are studied through the method of pulse radiolysis by electrons. HCOONa was introduced in all Np(6) and Np(7) solutions with pH>10.7 for suppression of OH+O2- and O-+O2 - O3-reactions. The Np(6) + H2O2 reaction was studied in the solutions, containing 1x10-4 mole.l Np(7) and saturated by H2O. It is found that change in pH from 9.2 to 13.7 decreases the velocity constants of all reactions from 104-105 up to 102-103 l (mole s)
