Muscat Chemicals is the largest manufacturer, supplier, exporter of RXSOL Manganese Dioxide, UAE Middle East, Barka, Sohar, Muscat, Oman
Manganese Dioxide is widely used for the Manganese, Iron Hydrogen Sulfide, arsenic, and Radium removal from water.
Iron and manganese are unaesthetic parameters present mostly in groundwater, causing unwanted precipitation and color.
Iron Removal from Water
Iron removal is based on the precipitation of dissolved iron (Fe2+) into its oxidized form (Fe3+), as Fe(OH)3 or Fe2O3.
Iron removal by physical-chemical way consists of iron oxidation by air followed by sand filtration, but other techniques exist as well:
Oxidation can be carried out by various chemicals like chlorine, ozone but is mostly done by compressed air.
Complex bound iron and manganese, e.g. complex bound with humic acids, can be very difficult to remove. In this case oxidation with ozone
can be a solution.
Manganese Removal from Water
For manganese removal only, Manganese dioxide (MnO2) is used as an adsorbent according to the following reaction:
Mn + MnO2 (s) --> 2 MnO (s)
Manganese oxides are then adsorbed on MnO2 grains. When all MnO2 has been consumed, it can be regenerated by sodium hypochlorite.
Manganese dioxide is a catalyst. So when there is a tiny bit of dissolved oxygen in the water, and the iron and manganese in the water
come in contact with the manganese dioxide, you get that catalytic reaction, and the iron and manganese are filtered out of the water.
Manganese dioxide is well known as a catalyst for selective oxidation of organic compounds; it is also a known catalyst for the oxidation of CO to CO2 at low temperatures.
Manganese dioxide catalyzes the decomposition of hydrogen peroxide into oxygen and water. Since manganese dioxide is a catalyst, it is not consumed in the reaction.
