Abstract
In this work five different treatment approaches were carried out to improve extraction and recovery of uranium and thorium from black sand and sea water matrices to be analyzed by ultra-sensitive ICP-MS technique. Quality control using standard IAEA reference was performed. These radionuclides were accurately determined in µg/L levels. The isotopic ratios; ^235U/^238U, ^234U/238U, ^238U/totalU and total U/^232Th were also assayed precisely, calculated and correlated. The results show values very close to the natural origin signature. The accuracy of separation and measured U isotopes and 232Th are of great importance for the national analytical techniques program.
