Manganese [ Print | Periodic Table ]
Location: Group 7, Period 4
Storage & Handling: Keep tightly sealed when not in use. Store and use at 20 ± 4°C. Do not pipet from container. Do not return portions removed for pipetting to container.
Chemical Compatibility: Stable in HCl, HNO3, H2SO4, HF, and H3PO4. Avoid basic media. Stable with most metals and inorganic anions in acidic media.
Stability: 2-100 ppb levels stable for months in 1% HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 1-5 % HNO3 / LDPE container.
Mn Containing Samples (Preparation & Solution): Metal (soluble in dilute acids); Oxides (soluble in dilute acids); Ores (dissolve with HCl. If silica is present, add HF and then fume off silica by adding H2SO4 and heat to SO3 fumes - dense white fumes).
