레이저유도파열검출 기술을 이용한 우라늄(VI) 가수분해물의 용해도 측정
Study on the Solubility of U(VI) Hydorlysis Products by Using a Laser-Induced Breakdown Detection Technique
Abstract
The solubility of U(VI) hydrolysis products was determined by using a laser-induced breakdown detection (LIBD) technique. The experiments were carried out at uranium concentrations in range from , pH values between 3.8 and 7.0, the constant ionic strength of 0.1 M and the temperature of . The solubility product of U(VI) hydrolysis products was calculated from LIBD results by using the hydrolysis constants selected in NEA-TDB. The solubility product extrapolated to zero ionic strength, was calculated by using a specific ion interaction theory (SIT). The spectral features of ionic species in uranium solutions were investigated by using a conventional UV-visible absorption spectrophotometer and a fluorophotometer, respectively, were dominant species at uranium concentration of .
