水杨酸对稀土元素反相纸层析的研究

STUDIES ON SALICYLIC ACID AS THE STATIONARY PHASES IN REVERSED PAPER CHROMATOGRAPHY FOR THE SEPARATION OF RARE EARTH ELEMENTS

以水杨酸的三氯甲烷溶液、三氯甲烷吡啶溶液和苯罗丹明Ｃ水溶液为固定相，以不同浓度的盐酸为展开剂，较系统地研究了３种固定相对镧、铈等１１种稀土离子的反相纸层析行为．实验表明，水杨酸的三氯甲烷吡啶溶液对某些稀土离子具有良好的萃取性能，并能成功地分离两种或两种以上的混合物．

Salicylic acid partly dissolved in chloroform.Chloroform pyridine and benzenl Luo Dan Min C water were used as stationary phases,hydrochloric acid solutions of different concentrations were used as the developer.The reverse paper chromatography behaviour of three stationary phases were studied systematicly for 11 rare earth ions,such as lanthanum,cerium and so on.As shown by study the extraction property of salicylic acid dissolved in chloroform pyridine was better for some rare earth ions.Salicysed paper chromatography to separate some rare earth ions mixtures.
