    The solid-liquid extraction of rare earths with 2-ethylhexyl phosphonic acid mono-2-ethyl-hexyl ester (P507, HL) in molten paraffin wax from hydrochloric acid has been studied. The mechanism of extraction is investigated by slope analysis method and the composition of the extracted complex is further determined by saturation volumetric method. The gelatinous extracted complex has been separated from the wax phase and studied by IR spectroscopy. From the IR spectra the chemical bonding in the extracted complex is discussed. The extraction constants K_(ex) of fifteen rare earths have been evaluated. The plots of log K_e, and pH (E = 50?) versus atomic number Z show the "tetrad effect? The mean separation factor of adjacent rare earths is 2.78. All experimental results agree with those of the extraction with P507 in n-dodecane. It proves that the same principles can be applied to both solid-liquid and liquid-liquid extraction systems. But the extraction, using molten wax as solvent, has some merits such as its accuracy, simplicity, rapidity, safety and economy.

    用斜率法确定了萃取机理,用饱和容量法确定了萃合物的组成。测定了15个稀土元素的萃取平衡常数K(cx)、logK(cx)和pH值(萃取率E=50%时)与原子序数间存在着明显的“四分级效应”。测得相邻元素间的平均分离因素为2.78。各项结果均与用P507的正十二烷溶液的萃取很一致,说明固-夜萃取和液-液萃取的原理是相的。但用熔化石蜡作溶剂研究萃取机理,存其一定的优越性,如准确、简单、快速、安全、经济等。
