Extraction chromatography of Am (III), Eu (III), Zn (II), and Cs (I), Using chromo sorb impregnated by 0..01 m 2-heptyl-2-methyl-nonanoic acid in benzene. Vol. 3

Extraction chromatography studies were carried out for Am(III), Eu(III), Zn(II), and Cs(I) using long carboxylic acid, 2-heptyl-2-methyl nonanoic acid in benzene as an extractant chromo sorb. This was selected to act as a solid support and it was impregnated with the extractant to obtain the stationary phase. The eluting agent used was 0.1 m H N O3. The investigation included primarily the extraction chromatography of the individual elements concerned and their elution peaks which were plotted. Group separation of the four elements into two pairs was obtained Am-Eu, and Zn-Cs. A mixture of the four elements was loaded on the column to achieve practically such promising group separations. 5 figs
