Ion specific chelating agents derived from beta -hydroxyhistidine, 4-(1-hydroxy-1-alkyl)imidazole and derivatives thereof

摘要

beta -hydroxyhistidine, 4-(1-hydroxy-1-alkyl)imidazole or derivatives thereof can be used as a bidentate ligand in the chelation of iron(III), Al(III), Cr(III), Ga(III) and the actinides(IV), such as plutonium 238. beta -hydroxyhistidine is found in a pyoverdine-type siderophore produced by Pseudomonas fluorescens 244.
