1000ug/mL PALLADIUM 500mL

Palladium

Location:  Group 10, Period 5
Atomic Weight:  106.42
Coordination Number:  6
Chemical Form in Solution:  Pd(H₂O)₆²⁺

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. Avoid contact with water soluble organics such as aldehydes since Pd²⁺ is easily reduced.

Stability:  2-100 ppb levels. 2 ppb Pd is stable for 1 day in 1% HNO₃ / LDPE container. 10 ppb is stable for 3 days in 1% HNO₃ / LDPE container. 100 ppb is stable for ≥ 5 months in 1% HNO₃ / LDPE container. 1-10,000 ppm solutions chemically stable for years in 1-5% HNO₃ / LDPE container.

Pd Containing Samples (Preparation & Solution):  Metal (soluble in HNO₃ or aqua regia); Oxides (soluble in HCl); Ores (dissolve in HCl / HNO₃).
