Top Suppliers Purity Chromium Oxide - Good Wholesale Vendors China of Chromic Acid Flakes – KaiLuoMu

short description:

Lead chrome green is the main coloring pigment in coating industry, and most green paints are made with this pigment. In addition, it is also used in paints and plastics. Its application range is very similar to that of lead chrome yellow. Due to the chromium yellow in the composition, attention should be paid to the toxicity of lead. Lead chrome green contains iron blue and lead chromate as oxidant.

Analysis method

Determination of chromic acid content in air: the sample was collected by filter, dissolved in sulfuric acid, and then determined by Colorimetry (NIOSH method) after adding diphenylcarbazide.

Determination of chromic acid content in water: the sample is extracted and determined by atomic absorption spectrometry or colorimetry.

Waste disposal method: after chemical reduction, the concentrated chromic acid waste liquid turns into trivalent chromium, and the pH value of the solution is adjusted to form precipitation, and the sediment is landfilled as chemical waste.


Chromic acid is the most common cleaning solution used in the laboratory. It has both acidity and oxidizability. It can remove the dirt and insoluble substances on the inner and outer walls of experimental instruments. Usually, the washing solution is obtained by adding potassium dichromate into concentrated sulfuric acid, but hexavalent chromium is harmful to the environment, and sometimes the instrument will be damaged in strong acid environment, so the application of chromic acid washing solution has been reduced.

Chromic acid can be used as oxidant. Many organic compounds can be oxidized by chromic acid, and many hexavalent chromium based oxidants have been developed. Jones reagent: aqueous solution of chromic acid, sulfuric acid and acetone, which can oxidize primary and secondary alcohols to corresponding carboxylic acids and ketones without affecting unsaturated bonds. Pyridinium chlorochromate: prepared from chromium trioxide and pyridine hydrochloride, can oxidize primary alcohol to aldehyde. Collins reagent: adduct of chromium trioxide and pyridine.

Chromic acid can also be used for chromium plating, high-purity metal chromium, pigment, mordant, medicine and coal contact, as well as in the production of some glazes and colored glass.
