However, since the resistance of metals, plastics and elastomers can be affected by concentration, temperature, presence of other chemicals and other factors. This information should be considered as a general guide rather than an unqualified guarantee. Ultimately, the customer must determine the suitability of the pump used in various solutions. All recommendations assume ambient temperatures unless otherwise noted. RATINGS — CHEMICAL EFFECT FOOTNOTES A — No effect—Excellent 1. P.V.C. — Satisfactory to 72 °F B — Minor effect—Good 2. Polypropylene — Satisfactory to 72 °F C — Moderate effect—Fair 3. Polypropylene — Satisfactory to 120 °F D — Severe effect—Not recommended 4. Nitrile — Satisfactory for “O” Rings 5. Polyacetal — Satisfactory to 72 °F 6. Ceramag — Satisfactory to 72 °F The ratings for these materials are based upon the chemical resistance only.

  • Chromate and the Environment: Removal and Utilization of Industrial Waste
    J. Chem. Chem. Eng. 10 (2016) 147-152 doi: 10.17265/1934-7375/2016.03.006 D DAVID PUBLISHING Chromate and the Environment: Removal and Utilization of Industrial Waste Fernando B. Mainier, Pedro Paulo B. Leite, Marcone F. Reis and Thiago Teobaldo Silva Engineering School, Federal Fluminense University(UFF), Niterói, Rio de Janeiro 24220-261, Brazil Abstract: Chromate and dichromate sodium as a function of oxidizer characteristics are used in several industrial areas; for example, in surface protection of coated parts of cadmium, zinc and aluminum (chromate coated treated), corrosion inhibitors, the treatment of leather, the manufacture of pigments, etc. However, the use of such products has been questioned due to the problems of toxicity and pollution that can be caused in the environmental. The Brazilian environmental agency has established that the concentrations of 2- chromate in water courses are less than 0.5 ppm. In order to reuse chromate (CrO4 ) from industrial effluent, laboratory experiments have been proposed based on chemical reduction or electrolytic processes, in order to transform these chromate ions in a final mix of oxides (in solid form), which can then be packed and sent to the production process of sodium chromate. The results of these experiments have become useful industrially (without regard to costs) considering the environmental reuse and the life cycle of the chemical compound. Key words: Chromate, dichromate, contamination, chemical reduction, electrolytic process. 1. Introduction waste, among others [1, 2]. In

  • Sodium Dichromate Product Stewardship Summary February 2012
    Sodium Dichromate Product Stewardship Summary February 2012 (Na2Cr2O7) Chemical Name: Sodium dichromate Chemical Category (if applicable): Inorganic chemical reagent Synonyms: Sodium bichromate; Chromic acid, disodium salt; Disodium dichromate(VI); Dichromic acid, disodium salt; Disodium dichromium heptaoxide; Sodium bichromate, anhydrous CAS Number: 10588-01-9 (anhydrate); 7789-12-0 (dihydrate) CAS Name: Sodium dichromate EC (EINECS) Number: 234-190-3 Other identifier (Please specify): GPS0064 Sodium dichromate is a strong oxidizing agent. Honeywell manufactures sodium dichromate for use by industry to treat and coat metal surfaces and for electroplating applications. Exposure can occur at either a sodium dichromate production facility or at other manufacturing, packaging or storage facilities that handle sodium dichromate. Persons involved in maintenance, sampling and testing activities, or in the loading and unloading of sodium dichromate packages are at risk of exposure, but worker exposure can be controlled with the use of proper general mechanical ventilation and personal protective equipment. Good manufacturing practices and industrial hygiene practices are also implemented to prevent or reduce exposure to sodium dichromate. Workplace exposure limits for hexavalent chromium compounds have been established for use in worksite safety programs. The general public or consumers have negligible exposure to sodium dichromate. Please see the MSDS for additional information. Sodium dichromate is an odorless solid in the form of orange-red crystals or powder. It is stable under normal conditions of use and storage. Sodium dichromate is not combustible, but it is a strong oxidizer that enhances the combustion of other substances. Avoid excess heat, combustible materials, and dust formation. Sodium dichromate reacts violently with hydrazine, anhydride, ethanol, and sulfuric acid.
