By Sahl, Jason W; Munakata-Marr, Junko; Crimi, Michelle L; Siegrist, Robert L ABSTRACT: For sites contaminated with chloroethene non-aqueous-phase liquids, designing a remediation system that couples in situ chemical oxidation (ISCO) with potassium permanganate (KMnO^sub 4^) and microbial dechlorination may be complicated because of the potentially adverse effects of ISCO on anaerobic bioremediation processes. Therefore, one-dimensional column studies were conducted to understand the...

Manganese is a chemical element in the periodic table that has the symbol Mn and atomic number 25. Notable characteristics Manganese is a gray-white metal, resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal is ferromagnetic only after special treatment. The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed. Mn2+ often competes with Mg2+ in...

Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn02) and is important as an ore of manganese. It is a soft, black, amorphous mineral, often with a granular, fibrous or columnar structure, sometimes forming reniform crusts. It has a metallic luster, a black or bluish-black streak, and readily soils the fingers. The specific gravity is about 4.8. Pyrolusite and rhodochrosite are among the most common manganese minerals. The metal is obtained by reduction of the oxide...
