摘　　要：本文采用ＨＤＥＨＰ／环己烷体系萃取锆和钼，并将两者分离以便测定锆的稳定同位素．此外，还研究了作为同位素稀释剂的ＺｒＯ２固体粉末的微波溶样法．Chemical separation of zirconium from molybdenum was investigated by using bis(2 ethylhexyl) hydrogen phosphate (HDEHP)/cyclohexane solvent extraction. Zr spike solution was prepared succesfully by microwave digestion of ZrO 2 powder in sulfuric acid instead of fussion technique, and the contamination due to fussion process was avoided. The results determined by ICP AES and ICP MS showed that the procedure was suitable for zirconium isotopic measurement.
