Molybdenum [ Print | Periodic Table ]
Location: Group 6, Period 5
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: Mo is received in a NH4OH matrix, giving the operator the option of using HCl or HF to stabilize acidic solutions. The MoO4-2 is soluble in concentrated HCl, MoOCl5-2, dilute HF / HNO3, MoOF5-2, and basic media MoO4-2. Stable at ppm levels with some metals, provided it is fluorinated. Do not mix with Alkaline or Rare Earths when HF is present. Stable with most inorganic anions, provided it is in the MoO4-2 chemical form.
Stability: 2-100 ppb levels stable (alone or mixed with all other metals that are at comparable levels) as the MoOF5-2 for months in 1% HNO3 / LDPE container. 1-10,000 ppm single element solutions as the MoO4-2 chemically stable for years in 1% NH4OH in a LDPE container.
Mo Containing Samples (Preparation & Solution): Metal (soluble in HF / HNO3 or hot dilute HCl); Oxide (soluble in HF or NH4OH); Organic Matrices (dry ash at 450°C in Pt0 and dissolve oxide with HF or HCl).
