Abstract	Nb is one of the trouble-some fission products in the reprocessing of nuclear fuels. In this paper, the extraction of Nb from 1, 2, 3, 4, 6 and 9N HNO3 solution by mixtures of TBP and DBP in dodecane are reported. Sums of the concentration of TBP and DBP are kept to 20%. When the concentrations of DBP are lower the 2×10-2%, distribution ratios are almost same, and ratios increase abruptly and the slope is about 2.5 at between 2×10-2 to 4×101%, then slope falls down to about 0.5. There is aging effect on mixture of TBP and DBP.
