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.
In this paper, we investigated the separation of several rare earths by reverse phase partition chromatography on the paper using the filter paper as the stationary phase and different concentrations of oxalic acid solution as the developing solvent (mobile phase) with toluene solution of bis (2-ethylhexyl) phosphate (HDEHP) Elements and uranium and thorium.Using 0.5M oxalic acid as a developing agent, uranium and thorium separation factor of 21; rare earth elements and thorium separation factor of 5. Therefore, the system is not suitable for individual elements of rare earth separation , But for the separation of thorium, uranium and thorium, the separation of the rare earth elements is effective.
