Ferric Oxide, Iron III Oxide SDS of Manufacturers
Synonyms: Iron III Oxide

Ferric Oxide USP NF
Ferric Oxide contains not less than 97.0 percent and not more than 100.5 percent of Fe2O3, calculated on the ignited basis.
Packaging and storage: Preserve in well-closed containers.
Identification: Dissolve 0.5 g in 50 mL of hydrochloric acid, and dilute with water to 200 mL: the solution so obtained responds to the test for Ferric Salts under Iron..
Water-soluble substances: Digest 2.0 g in 100 mL of water on a boiling water bath for 2 hours, filter, and wash the filter with water. Evaporate the filtrate and washings, and dry the residue at 105 for 1 hour: the weight of the dried residue is not more than 20 mg (1.0%).
Acid-insoluble substances: Digest 2.0 g in 25 mL of hydrochloric acid by boiling for 20 minutes. Add 100 mL of hot water, and filter quantitatively through a tared filtering crucible, with the aid of hot wash water, until the filtrate tests negative for chloride. Dry the crucible and contents at 105 for 1 hour: the residue weighs not more than 6 mg (0.3%).
Organic colors and lakes: Place 1.0 g in each of 3 beakers, and add 25 mL of each of the following reagents, respectively: 1-chloronaphthalene, alcohol, and chloroform. Heat the beakers containing alcohol and chloroform just to boiling. Heat the other beaker on a boiling water bath for 15 minutes, with occasional swirling. Filter the contents of the beakers through retentive, solvent-resistant filter paper. If any of the filtrates shows visible turbidity, centrifuge for 15 minutes. Record the spectra against respective solvent blanks in 1-cm cells from 350 to 750 nm. No peak, above the noise level, with a slope greater than +0.001 absorbance unit per nm is found.
Mercury: The limit is 3 µg per g.
Limit of arsenic: The limit is 3 µg per g.
Limit of lead: The limit is 0.001%. (0.001%).
Assay: Digest about 1.5 g of Ferric Oxide, accurately weighed, in 25 mL of hydrochloric acid on a water bath until dissolved. Add 10 mL of hydrogen peroxide and evaporate on a water bath almost to dryness in order to volatilize all hydrogen peroxide. Dissolve the residue by warming with 5 mL of hydrochloric acid; add 25 mL of water; filter into a 250-mL volumetric flask, washing the filter with water; and add water to volume. Transfer a 50-mL aliquot to a glass-stoppered flask, add 3 g of potassium iodide and 5 mL of hydrochloric acid, and insert the stopper into the flask. Allow the mixture to stand for 15 minutes, add 50 mL of water, and titrate the liberated iodine with 0.1 N sodium thiosulfate, using starch as the indicator. Perform a blank test with the same quantities of reagents and in the same manner, and make any necessary corrections. Each mL of 0.1 N sodium thiosulfate is equivalent to 7.985 mg of Fe2O3. Ignite about 2 g of Ferric Oxide at 800 ± 25 to constant weight as directed under Loss on Ignition 733 , to enable calculation of the percentage of Fe2O3 on the ignited basis. [NOTE—Ignited Ferric Oxide is hygroscopic.]
