A paper chromatographic scheme for the identification of metallic ions

Abstract

Presents a scheme for the identification of metallic ions through paper chromatography.

Cation analysis with thin layer chromatography

“…It consists of a 400-ml beaker containing two strips of Whatman No. 1 paper measuring approximately 3 X 26 cm. The strips are placed in the beaker so that they cross at the base and continue up the walls, each in the form of a U (Fig.…”

“…Reported here is an adaptation of the familiar technique of thin layer chromatography (TLC) to an undergraduate laboratory operation for cation analysis. While several such schemes employing paper chromatography have been devised (1)(2)(3)(4), a major portion of the work with TLC has been devoted to the separation of organic materials (5)(6)(7)(8). One of the more comprehensive works published on cation analysis with TLC is that of Seiler, et al (9)(10)(11)(12).…”

Chromatography

“…Comprehensive analytical schemes have been devised (291, 973). Frequently, derivatives, such as oxalates (1083, 1084), tartrates (1082, 1083), citrates (1083, 1085), thiocyanates (579,1225), sulfides (951), 8-quinolinolates (629,758,795), thiourea (80, 655), nitrato (1245),…”
