Manganese Dioxide Product Stewardship Summary February 2012 Manganese Dioxide Product Stewardship Summary February 2012 MnO2 Chemical Name: Manganese Dioxide Chemical Category (if applicable): Inorganic metal compound Synonyms: Manganese(IV) oxide; Manganese black; Manganese peroxide; Manganese Binoxide; Manganese oxide; Cement black; and MnO2 CAS Number: 1313-13-9 CAS Name: Manganese dioxide EC (EINECS) Number: 215-202-6 Other identifier (Please specify): GPS0058 Honeywell manufactures manganese dioxide for industrial use in chemical processing, catalyst additives and as a curing additive in long-term elasticity sealants with liquid polysulfide polymers. The primary risk of worker exposure to manganese dioxide is by inhaling its dust or fume during its production, processing, storage and use. The risks of exposure can be minimized when exposures to manganese dioxide are controlled with process enclosures, local exhaust ventilation, general dilution ventilation, and use of personal protective equipment. Workplace exposure limits have been established for use of manganese compounds in worksite safety programs. Please see the MSDS for additional information. Since the use of manganese dioxide is confined to industrial settings, the risk of exposure to the general public including consumers is considered negligible. Manganese dioxide is an odorless solid in the form of a brown powder. Manganese dioxide is not combustible, but it is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. Contact with oxidizable substances (sulfur, sulfides, phosphids, hypophosphites, chlorates, peroxides, aluminum powder, rubidium acetylide, potassium azide, chlorine trifluoride) may cause extremely violent combustion. It reacts with hydrochloric acid to form corrosive chlorine gas. Toxic metal fumes may form when heated to decomposition. Decomposition products include oxygen and oxides of manganese. Exposure to manganese dioxide dust can irritate the eyes, skin, nose, throat and lungs. Prolonged or repeated exposure to manganese dioxide dust or fume may produce effects on the lungs and central nervous system, resulting in increased susceptibility to bronchitis, pneumonitis and neurologic, neuropsychiatric disorders (manganism). Manganese dioxide is not considered carcinogenic to humans. This product stewardship summary is intended to give general information about the chemical or categories of chemicals addressed. It is not intended to provide an in-depth discussion of all health and safety information. Additional information on the chemical is available through the applicable Material Safety Data Sheet which should be consulted before use of the chemical. The product stewardship summary does not supplant or replace required regulatory and/or legal communication documents. Statements concerning use of our products are made without warranty that any such use is free of patent infringement and are not recommendations to infringe any patent. Manganese dioxide is not soluble in water and is considered practically nontoxic to freshwater organisms (e.g., fish, invertebrates and algae) based on results of acute aquatic toxicity testing.

The crosslinked copolymeric hydrogel based on 2-acrylamido-2-methylpropane sulfonic acid-co-acrylic acid (AMPS/AA) was used as template to encapsulate the metal oxides by introducing the metal cations followed by redoxy reaction into the gel networks. The chemical, crystal structures, morphology and metal oxide contents were investigated using different spectroscopy and instrumental analyses. The ability of AMPS/AA metal oxide nanocomposites to remove different concentrations of textile cationic dye water pollutants such as crystal violet (CV) from aqueous environments was investigated using UV-visible measurements. The adsorption measurements confirmed the AMPS/AA metal oxide nanocomposites have high efficiency of to remove 1.5 g/L of CV during short time ranged between 20 and 60 minute. The kinetic study indicated that the adsorption process of CV adsorbate using AMPS/AA metal oxide nanocomposite adsorbents obey chemical adsorption mechanism.

  • Reduction of Manganese Oxides by Methane-Containing Gas

E-mail: [email protected] (Received on February 12, 2004; accepted in final form on June 8, 2004) The paper presents results of reduction of pure manganese oxides by methane containing gas in non- isothermal and isothermal experiments and reduction mechanisms. The extent and rate of manganese oxide reduction were determined by on-line off-gas analysis using a mass-spectrometer in a fixed bed labo- ratory reactor in the temperature range 1 000–1 200°C at different gas compositions. Manganese oxides were reduced to carbide Mn7C3. High extent and rate of reduction by methane-con- taining gas in comparison with carbothermal reduction were attributed to high carbon activity in the reduc- ing gas, which was in the range 15–50 (relative to graphite). The rate of reduction of manganese oxide in- creased with increasing temperature. Increasing methane content in the reducing gas to 10–20 vol% CH4 favoured the reduction process. Increase in hydrogen partial pressure had a positive effect on the reduction rate. Addition of carbon monoxide to the reducing gas retarded the reduction process. The addition of Fe3O4 to manganese oxide increased the rate of reduction.

  • Abstract Catalytic Performance And
    ABSTRACT CATALYTIC PERFORMANCE AND CHARACTERIZATION OF ZN-DOPED CRYPTOMELANE-TYPE MANGANESE DIOXIDE FOR ETHANOL OXIDATION by Lulu Jiang Cryptomelane (KMn8O16) was prepared by two methods: 1) a sol-gel method, and 2) a proprietary method that uses alkaline battery waste as a starting material. These cryptomelane materials were investigated as volatile organic carbon (VOC) oxidation catalysts and compared. To better understand the roles of processing steps on the physical characteristics and catalytic activity, the effects of zinc dopant and calcination temperature were studied with the sol-gel cryptomelane materials. Zinc dopant was included as a test variable because it is present in alkaline battery waste, and cyrptomelane prepared from battery waste also contains zinc (<5 wt%). The oxidation of ethanol was used to assess catalytic activity of the cryptomelane materials. It was found that cryptomelane-based manganese dioxide prepared by both the sol-gel method and from battery waste can be used as catalysts in the catalytic oxidation of ethanol in air. The zinc dopant (<5 wt%) has very little impact on catalytic activity, although it has some impact on the morphology and crystallinity of the materials. Calcination temperature, however, which impacts the surface area of the material, has a much more significant role, where the higher the calcination temperature, the lower the surface area, and hence, the lower the catalytic activity.

Clemson University, 2016 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Chemistry in the College of Science at the University of Central Florida Orlando, Florida Fall Term 2020 © 2020 Morgan Snyder ii ABSTRACT Anthropogenic activities, such as uranium mining and the production of nuclear energy and nuclear weapons, have led to significant uranium contamination of the environment, leaving populations vulnerable to negative health effects. In order to effectively remediate uranium contamination, the mobility of uranium in the environment and its natural attenuation through sorption with active mineral phases, needs to be studied in depth first. This study aims to determine how U(VI) mobility is affected by manganese oxides in the presence and absence of siderophore Desferrioxamine-B (DFOB).

This process generates large amounts of furnace dust that is environmentally problematic for storage. Due to its fineness and high volatile content, this furnace dust cannot be recirculated through the process, either. Conventional MnO2 production requires the pre-reduction of low-grade ores at around 900 ◦C to convert the manganese oxides present in the ore into their respective acid-soluble forms; however, the furnace dust is a partly reduced by-product. In this study, a hydrometallurgical route is proposed to valorize the waste dust for the production of battery-grade MnO2.
