Sequential spectrophotometric determination of chromium(III) and chromium(VI) using flow injection analysis
(1985-12-01)
A flow injection analysis (FIA) procedure for the speciation of Cr(III) and Cr(VI) using the 1,5-diphenylcarbazide (DPC) method is presented. As Cr(III) does not interfere in the Cr(VI) - DPC reaction, both Cr(VI) and total ...

Characterization of silica supported chromium complexes
(Planta Piloto de Ingeniería Química, 2000-03)
The Cr/SiO2 catalysts were prepared via the deposition of mononuclear and binuclear chromium (III) ammine complexes on silica. The influence of chromium loading and calcination temperatura upon the type of species formed ...
The significance and determination by image analysis of microcrack density in hard chromium plating
(2008-04-01)
It is well known that the microcrack density is a fundamental parameter in hard chromium electroplating. The chemical and mechanical properties of this coating are widely dependent on its microcrack density. In this paper ...

Preconcentration and speciation of Cr(III) and Cr(VI) in water samples using amberlite XAD-16 resin and determination by flow injection-flame AAS
(Perkin-Elmer Corporation, 2002-03)
A method for the pre-concentration and speciation of chromium was developed. On-line pre-concentration and determination were obtained using flame atomic absorption spectrometry (FAAS) coupled with flow injection (FI). To ...
