Basicity Separation of Th, U and Ce from their nitrate solution was investigated under ultrasonic effect. The intensity of the field and wave frequency employed were respectively 2.0-8.2W/㎠ and 400, 1200KC. It was found from the investigation that ultrasonic field considerably improved the separation of Th from U over conventional mechanical stirring. The effect of ultrasonic field intensity on the precipitation curve was such that the precipitation pH shifted as the intensity increased. Hence, a broader precipitation pH range between Th and U was observed when ultrasonic field was applied, i.e. from 0.4 pH unit (mechanical stirring) to 1.3 pH unit (at 4.1W/㎠ of ultrasonic intensity). The effect of wave frequency on the precipitation pH was small but tendency of flocculating the precipitated particles was observed to be noticeable at the high frequency.
