[en] A method for determination of Ti, V and Mo in nuclear purity UO₂ by ICP-AES is described. The sample charged into the DHDECMP extraction resin chromatographic column was separated at a flow rate of 0.5 mL/min with 3 mol/L HNO₃ as a medium. The uranium was absorbed on the chromatographic column while the three impurity elements remained in the effluent solution. Using the Jarrell-Ash Model 975 ICP direct reading spectrometer the Ti, V and Mo in the effluent solution was determined with the determination limits of 0.08 x 10^-6 to 0.6 x 10^-6. The RSD was better than 14% and the recovery of 94% to 99% was obtained
