Rutter开始应用圆形纸层析法分离无机离子.优点为层析时间较短, 仪器亦较简单, 且具较好的重现性.为此著者根据前人的研究, 利用国产滤纸, 以圆形纸层析法系统研究定性分析中各组阳离子的分离.从中选出一套适于各组离子分离的展开剂, 以利分析.

Experiments have shown that 96% ethanol-2N acetic acid(8:2), glacial acetic acid-pyridine-concentrated hydrochloric acid(80:6:20), n-butanol-pyridine-water(10:1:2), tert-butanol-acetone-water-6N nitric acid-acetylacetone(4:4:1.1:0.45:0.45) and tert.-butanol-chloroform-SN hydrochloric acid-acetylacetone(4.5:4.5:0.8:0.2) are satisfactory eluents for group Ⅰ and Ⅱ, group Ⅲ, group Ⅳa, group Ⅳb and group Ⅴ of cations respectively, by circular paper chromatographic method with a Chinese brand filter paper(Quantitative grade manufactured by the Hsin-Hua Paper Factory, Hangchow).
