Phosphate coatings are usually applied to carbon steel, low-alloy steel and cast iron. The coating is formed with a solution of iron, zinc or manganese phosphate salts in phosphoric acid, and is applied by either spraying the solution onto the substrate, or immersing the substrate into the solution.

The use of manganese compounds stretches back more than 17,000 years. Ancient cave paintings, including those in Lascaux France, derive their color from manganese dioxide. Manganese metal, however, was not isolated until 1774 by Johan Gottlieb Gahn, three years after his colleague Carl Wilhelm Scheele had identified it as a unique element.

2.2. Adsorption experiments. Sodium perchlorate (NaClO 4 ·H 2 O) at 0.01 M was used to maintain the background ionic strength. pH was adjusted during adsorption using 0.1 M NaOH and 0.1 M HNO 3 to achieve pH variation in the range of ±0.1. All the batch experiments were proceeded in triplicate at the same time. Blank control experiments without the addition of adsorbents confirmed that no ...

The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from -3 to +7 are observed. Mn 2+ often competes with Mg 2+ in biological systems. Manganese compounds where manganese is in oxidation state +7, which are restricted to the oxide Mn 2 O 7 and compounds of the intensely purple permanganate anion MnO 4 −, are powerful oxidizing agents.

Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. Phosphates can be grouped as: primary phosphates that have crystallized from a liquid; secondary phosphates formed by the alteration of primary phosphates; and rock phosphates formed from phosphorous-bearing organic material.

Manganese definition is - a grayish-white usually hard and brittle metallic element that resembles iron but is not magnetic and is used especially in alloys, batteries, and plant fertilizers.

May 13, 2015· Two phylogenetically divergent genes of the new family of dye-decolorizing peroxidases (DyPs) were found during comparison of the four DyP genes identified in the Pleurotus ostreatus genome with over 200 DyP genes from other basidiomycete genomes.
