Synthesis and properties of a new analytical reagent, 2-hydroxy-3-nitrosonaphthalene-1-carbaldehyde
摘要:
A new nitroso derivative of beta-naphthol, 2-hydroxy-3-nitrosonaphthalene-1-carbaldehyde, has been synthesized, and its structure has been studied by H-1 NMR and IR spectroscopy. This compound can be immobilized on a fibrous support and used as specific analytical reagent for the determination of metal ions, in particular cobalt(II). A procedure for the determination of cobalt(II) in wastewater has been proposed.
