Vanadium [ Print | Periodic Table ]
Location: Group 5, 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: Soluble in HCl, HNO3, H2SO4, HF, H3PO4, and strong 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.
V Containing Samples (Preparation & Solution): Metal (fusion with NaOH or KOH in Ni0 or Na2CO3 / KNO3); Oxides (V2O3 - use HCl; V2O4 - use HCl or HNO3; V2O5 - use conc. acids); Ores (Na2CO3 / KNO3 in Pt0 (caution - nitrates attack Pto) followed by water extraction of fuseate); Organic Matrices (ash at 450°C followed by dissolving according to V2O5 above).
