紙上色层分离已广泛的用于无机分析中。紙上色层分离的各种技术亦在迅速的发展。近年來反相分配色层的技术也用于紙上色层分离中,例如以三辛胺(tri-n-octylamine),三辛氧化憐(tri-n-octyl phosphine oxide)和磷酸三丁酯浸过滤紙的紙上色层。其中磷酸三丁酯为反相的紙上色层仅作了极其簡单的报导,并未进行詳細的研究,亦无具体結果。反相紙上包层分离的特点是以无机物质的溶液如酸和盐等作为流动相,有机物质浸涂在色层紙上作为固定相。因此,流动相的組成和酸度比一般正相紙上色层易于控制,致使分离所得的R_f值此較稳定,卽再现性好。本工作的目的試图将国产撫順东捷造紙厂“白雪”牌定性滤紙,用磷酸三丁酯(TBP)浸泡一定时间后,以硝酸作为流动相,研究某些四阶元素的移动行为,結果表明:钛和锆及钍和锆能彼此分离。
Paper color separation has been widely used in inorganic analysis. Paper color separation of the various technologies are also rapidly developing. In recent years, the technique of reversely partitioning a color layer has also been used in the color separation of paper, for example, tri-n-octylamine, tri-n-octyl phosphine oxide and tributyl phosphate Paper color filter layer. Tributyl phosphate, which is an inverting paper color coat, is only a very simple report and has not been studied in detail nor has been shown to have any specific result. Reverse-coated paper is characterized by the separation of the coating of inorganic substances such as acids and salts as the mobile phase, organic matter dip coating on the paper as a stationary phase. Therefore, the composition and acidity of the mobile phase are easier to control than those of the normal positive-tone paper, resulting in a more stable Rf value and better reproducibility. The purpose of this work attempts to Fushun Dongjie paper mills, “Snow” brand qualitative filter paper, soaked with TBP (TBP) for a certain period of time, the use of nitric acid as mobile phase to study the movement of some fourth-order elements of the results It shows that titanium and zirconium and thorium and zirconium can be separated from each other.
