“…The production of the metal from mining of its ores involves large amounts of waste that increases the possibility of groundwater contamination. Design and synthesis of appropriate ligands that can be used for the analysis and extraction of the cation is essential for solving part of these problems and extensive studies have been dedicated to developing new sensitive and selective spectrophotometric reagents and improving existing procedures in order to develop simple and accessible procedures for the analysis of the cation [1][2][3][4][5][6][7][8][9][10][11] that will enable its detection in waste water.…”

Several ligands were designed as plausible reagents for the spectrophotometric analysis of uranyl in aqueous solutions. The ligand L 2À 3 = 3,3′-(ethane-1,2-diylbis(methylazanediyl))bis(methylene)bis(4-hydroxybenzenesulfonate) was found to fit best the requirements. The results point out that carboxylate substituents compete with the phenolate substituents as binding sites to the central uranium cation and therefore decrease the usefulness of ligands containing both carboxylate and phenolate substituents as analytical spectrophotometric reagents.
