| Abstract: | In this paper, a new TLC method is described, TLC behaviour of RE(Ⅲ), Ti(Ⅳ), Zr(Ⅳ), Nb(Ⅴ) and U(Ⅵ) in oxalic acid-alcohol rystems on C-SbA-P-SCP impregnated thin-layer plate was studied. Aseries of effective separation of binary and ternary mixtures were achieved. The method is simple, rapid and intuitional.Based on the experimental results, an empirical formula was proposed: Rf=a-b104/Z2r0 where Z and r0 are the atomic number and the bare ion radius of lanth-anide, respectively.The intercepts, slopes and linear relative coefficients(r) of curves were calculated for various developers. |
