摘要/Abstract

摘要： 本文报导了一种新的薄层色谱法,研究了稀土(Ⅲ)、钛(Ⅳ)、锆(Ⅳ)、铌(Ⅴ)和铀(Ⅳ)的TLC行为,有效地分离了一系列二元及三元混合物.方法简便、快速、直观.根据实验结果,推荐了镧系元素的原子序数(Z)、离子裸半径(r°)与R_f值的经验公式.计算了在各种展开剂中曲线的截距、斜率和线性相关系数(r).

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: R_f=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.
