本實驗對利用逆相薄層色層分析法研究稀土元素之各影響條件作較廣泛之探討，如惰性支持物之影響，有機磷化合物構造與濃度之影響，金屬量之變化，各種礦物酸不同濃度之影響以及溫度變化對分析法之影響等，以期由此能對應用此分析法分離稀土元素所須較佳條件之尋找有所助益。

The use of the neutral organophosphorus compounds di (2-ethylhexyl) phosphate (HDEHP), di-n-butyl phosphate (DBP) and tri-n-butyl phosphate (TBP) as organic phase in the reversed-phase partition thin-layer chromatography of rare earth nitrates, chlorides, and perchlorates was investigated. R_I and R_M values are reported as a function of the acid concentration of the mobile phase for the movement of rare earth metal ions on thin-layer of silica gel, cellulose powder, or aluminum oxide impregnated with HDEHP, DBP, or TBP. The effects of inert support, structure and concentration of organophosphorus compounds, variations in the amounts of rare earth compounds used, various Concentration of different mineral acids as well as change of temperature were discussed.
