1000ug/mL ZIRCONIUM 125mL for AA

Zirconium Expanded View

Zirconium

Location:  Group 4, Period 5
Atomic Weight:  91.224
Coordination Number:  6, 7, 8
Chemical Form in Solution:  Zr(F)6-2
(coordination numbers in green are observed less frequently)

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 concentrated HCl, HF, H2SO4 (very hot) and HNO3. Avoid H3PO4 and neutral to basic media. Unstable at ppm levels with metals that would pull F- away (i.e. - do not mix with Alkaline or Rare Earths or high levels of transition elements unless they are fluorinated). Stable with most inorganic anions but precipitation with phosphate, oxalate, and tartrate with a tendency to hydrolyze forming the hydrated oxide in all dilute acids except HF.

Stability:  2-100 ppb levels stable (alone or mixed with all other metals that are at comparable levels) as the Zr(F)6-2 + Zr(OH)4F2-2 for months in 1% HNO3 / LDPE container. 1-10,000 ppm single element solutions as the Zr(F)6-2 chemically stable for years in 2-5% HNO3 / trace HF in an LDPE container.

Zr Containing Samples (Preparation & Solution):  Metal (soluble in H2O / HF / HNO3); Oxide unlike TiO2, the ZrO2 is best fused in one of the following ways (Na2O2 in Ni0, Na2CO3 in Pt0 or Borax in Pt0); Organic Matrices (dry ash at 450&degC in Pt0 and dissolve by fusing with Na2CO3 and dissolving in HF / HNO3 / H2O).
