Effects of the different conditions of uranyl and hydrogen peroxide solutions on the behavior of the uranium peroxide precipitation

► The dynamic precipitation characteristics of UO4 in different conditions were characterized by measuring absorbance and particle size in the precipitation solution. ► The precipitation solution conditions affected the precipitation characteristics of induction time, precipitation rate, overall precipitation time, and particle size. ► With increases in both pH and ionic strength, the induction time was prolonged, and the individual particle size decreased. ► The uranium concentration and precipitation rate affected the final morphology of the UO4 precipitate.
