摘要：
According to Lloyd [1], Pu(IV) undergoes oxidation to Pu(VI) at an accelerated rate due to Ru(III) present as Ru(NO)-complexes in nitric acid solution. To be able to study this effect in more detail kinetic measurements were performed using Laser Raman Spectroscopy (LRS) and spectrophotometry as analytical methods. In these experiments the parameters temperature, Ru(III)-concentration, Pu(IV) concentration, HNO3 concentration and F- concentration were investigated. From the results obtained reaction orders were estimated as far as possible, using the method of initial rates according to van't Hoff.
