本文探讨以磷酸二(2-乙代己基)酯(HDEHP)的甲苯溶液处理滤纸作为固定相,不同浓度的草酸溶液作展开剂(流动相)的纸上反相分配色层法分离若干希土元素以及铀和钍.找出用0.5M草酸作展开剂时,铀和钍的分离因数为21;希土元素和钍的分离因数为5.因此本体系虽不适于个别希土元素的相互分离,但对于钍、铀分离以及钍、希土元素的分离却有效.

The authors have investigated the reversed-phase paper chromatographic separation of rare earth elements.thorium and uranium.Di(2-ethylhexyl)-phosphoric acid (HDEHP) dissolved in toluene was applied to Whatman No.1 paper,and subsequently,the solvent was driven off with hot air current.The ions studied were applied onto the paper and eluted with various concentrations of oxalic acid (0.1-1.0 M).
