摘要：

Separation of lanthanum(III) from iron(III), molybdenum(VI), vanadium(V), chromium(VI), titanium(IV), bismuth(III), zirconium(IV), scandium(III), uranium(VI), and beryllium is achieved by solvent extraction with mesityl oxide from sodium salicylate solution (0. 1 M adjusted to pH 7). Lanthanum from the organic phase is stripped with water and determined photometrically as its arsenazo complex at 570 nm. The extracted species is trisolvated i. e. La(HOC//6H//4COO)//3 multiplied by (times) 3MeO. The results of separation are reported.
