or oxidation, or bychelating agentsthat are actively absorbed. Although soluble nickel compounds (nickel sulfate, nickel chloride, and nickel nitrate) are better absorbed than relatively insoluble ones, the contribution of some slightly soluble compounds (nickel metal, nickel carbonate, nickel oxides, ...
chromium sesquioxide: A green crystallinewater-insoluble salt, Cr2O3; r.d. 5.21;m.p. 2435°C; b.p. 4000°C. It is obtainedby heating chromium in astream of oxygen or by heating ammoniumdichromate. The industrialpreparation is by reduction ofsodium dichromate with carbon.Chromium(III) oxid...
Ion chromatography (IC) is a process to separate ions or polar molecules based on their affinity to the ion exchanger. The water soluble charged molecules bind to oppositely charged moieties by forming covalent bonds to the insoluble stationary phase (Luqman and Inamuddin, 2012). IC is useful ...
A large number of chromium(III) compounds are known, such as chromium(III) nitrate, chromium(III) acetate, and chromium(III) oxide.[29] Chromium(III) can be obtained by dissolving elemental chromium in acids like hydrochloric acid or sulfuric acid, but it can also be formed through the red...
biomass accumulation appears relatively invariant to the framework used and comparable to growth with a model iron oxide (ferrihydrite). Our results are also in agreement with previousShewanellagrowth studies on soluble/insoluble iron substrates, which showed that cell yields were similar regardless of ...
X-ray microprobe analysis indicated the heterogeneous distribution of insoluble CrIII and soluble ReVII species in saltstone. There was no apparent trend in the release of chromate (CrVIO 42-) and perrhenate (ReVIIO4 -) as a function of depth (up to few cm). However, the chemical ...

Exposure limits TLV-TWA: chromium metal 0.5 mg/m3 (ACGIH and MSHA), 1 mg/m3 (OSHA); Cr(II) and Cr(III) compounds 0.5 mg/m3 (ACGIH); Cr(VI) compounds, water soluble and certain water insoluble, 0.05 mg/m3 (ACGIH). Stability: Stable. Incompatible with carbonates, strong bases, miner...
It appears as dark red rhombic crystals or purple-red flakes. Soluble in water, alcohol, sulfuric acid and ether, do not dissolve in acetone. Uses Chromium(VI) oxide is used for chromium plating; copper stripping; as an oxidizing agent for conversion of secondary alcohols into ketones (Jones...
