1,2-diaminobenzene derivatives for the determination of selenium by gas chromatography

The synthesis and characterisation of two new substituted 1,2-diaminobenzenes for use as ligands to form piazselenols by reaction with selenium(IV) in acid solution and their gas chromatographic properties is described. The use of these ligands for the determination of selenium in a range of samples...

Description
Summary:The synthesis and characterisation of two new substituted 1,2-diaminobenzenes for use as ligands to form piazselenols by reaction with selenium(IV) in acid solution and their gas chromatographic properties is described. The use of these ligands for the determination of selenium in a range of samples was made. A comparison with already suggested ligands in terms of detection limits and applicability clearly shows the supremacy of the newly synthesized ligands.
