摘要：

Extraction of cerium-group lanthanide(III) nitrates (La-Gd) with trialkylbenzylammonium nitrate in toluene at 298.15 K and pH 2 was studied. Extraction isotherms are described with regard to formation of the compounds (R4N)(i)[Ln(NO3)(3+i)] (i = 2, 3 for Pr, Nd, Sm, Eu, and Gd; i = 3, 4 for La and Ce) in the organic phase. Extraction constants were calculated They decrease in the La-Gd series.
