Cerrai[1,2]等曾研究了二(2-乙基己基)磷酸(HDEHP)对稀土元素的反相层析,并用斜率法测定了萃合物组成.Cvjelicanin[3]用反相层析研究了二丁基磷酸对铍、镧及铈的萃取机理和平衡常数.我们以往的研究结果说明,配位体结构的极性效应和空间效应对分离金属离子的反相层析行为与液液萃取极相似[4,5].

The separation behaviour of salts of rare earths elements and their oo-existing ones by 2-ethylhexylphosphonio acid mono (2-ethylhexyl) ester (P507) was studied by using reversed phase paper chromatography and compared with the data obtained from solvent extraction. The composition of the extraoted species was discussed on the basis of the slope method in reversed phase paper chromatography.
