Journal ArticleDOI
A new reagent for the spectrophotometric microdetermination of cadmium
TL;DR: In this paper, a simple, rapid, and sensitive spectrophotometric micro determination of cadmium in aqueous solution was carried out at pH 12.3 ± 0.2.
Journal ArticleDOI
Spectrophotometric microdetermination of zinc in the presence of copper and iron
TL;DR: In this article, a simple, rapid, and sensitive procedure for the spectrophotometric microdetermination of zinc in the presence of iron and copper is proposed, where the zinc-DPPH complex is formed at pH = 12 ± 0.2 and measured at 442 nm no more than 15 min after the addition of DPPH.
Journal ArticleDOI
Spectrophotometric study of the copper(II)-2,2′-dipyridyl-2-pyridylhydrazone complex formation
TL;DR: In this article, the reaction of copper(II) ions with 2,2′-dipyridyl-2-pyridisylhydrazone (DPPH) has been studied.
Journal ArticleDOI
A spectrophotometric study of the color reaction of zinc with 2,2′-dipyridyl-2-pyridylhydrazone (DPPH)
TL;DR: In this paper, a spectrophotometric study of the zinc complex with 2,2′-clipyridyl-2-pyridishydrazone (DPPH) is presented, where the optimal formation conditions, the composition, and the overall apparent instability constant of the yellow, water-soluble zinc complex are studied.
Journal ArticleDOI
Spectrophotometric microdetermination of some anthraquinone derivatives separated by thin layer chromatography
TL;DR: A method for the spectrophotometric determination of anthraquinone derivatives, after separation on thin layers of silica gel, has been developed as mentioned in this paper, which can be used to identify photo-oxidation products of anthracene.
