Preparation of Chromium (III) Phthalate via Chromium (VI) Oxide using tertiary amyl alcohol as a solvent
نویسنده
چکیده
Complexes [CrO2 (C8H5O4) (H2O) 3] and [CrO2 (C8H5O4) (H2O) 3] .H2O were prepared by reduction of CrO3 at room temperature by ethanol in the presence of phthalic acid (H2pht) yield solution that contains monomeric and dimeric Cr (III) complexes. A solution H2pht/Cr molar ratio of 1:1 and 1:2 is indefinitely stable towards precipitation. Their analysis were done by using elemental (C and H), ICP-OES (for Cr %), UV-Vis, FTIR, 1HNMR and Fast Atomic Bombardment (FAB) Mass spectrometry, where as thermal behaviour was investigated by DSC.

The use of an inorganic phase in water-in-oil (w/o) microemulsion has recently received considerable attention for preparing metal oxide nanoparticles. This is a technique, which allows preparation of ultrafine metal oxide nanoparticles within the size range 40 to 80 nm. Preparation of nano chromium (III) oxide studied investigated in the inverse microemulsion system. Therefore the nucleation o...
متن کاملNon-destructive rapid analysis discriminating between chromium(VI) and chromium(III) oxides in electrical and electronic equipment using Raman spectroscopy.
The European Union has banned chromium(VI) compounds in electrical and electronic equipment (EEE), such as chromate conversion coating films. Chromium(III) compounds are not banned. Using Raman spectroscopy without any preparation, we distinguished chromium(VI) oxide from chromium(III) oxide and chromium(III) hydroxide in chromate conversion coating films. Raman bands of chromium(VI) oxide were...
متن کاملPreparation and Characterization of Chitosan Thin Films on Mixed-Matrix Membranes for Complete Removal of Chromium
Herein we present a new approach for the complete removal of Cr(VI) species, through reduction of Cr(VI) to Cr(III), followed by adsorption of Cr(III). Reduction of chromium from water is an important challenge, as Cr(IV) is one of the most toxic substances emitted from industrial processes. Chitosan (CS) thin films were developed on plain polysulfone (PSf) and PSf/TiO2 membrane substrates by a...
