Location: Group 15, Period 6
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, and HF. Avoid basic media forming insoluble hydroxide. Stable with most metals and inorganic anions in acidic media. Many salts that are insoluble in water are soluble in HCl, HNO3 and HF. The major problem with Bi3+ is its tendency to hydrolyze at higher concentrations or in dilute acid. Nitric acid solutions should be 5% to hold the Bi in solution in the 100 to 10000 µg/mL concentration range.
Stability: 2-100 ppb levels stable for months in 1 % HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 5 - 7% HNO3 / LDPE container.
Bi Containing Samples (Preparation & Solution): Metal (soluble in HNO3); Oxides (soluble in HNO3); Alloys (dissolve in conc. 4:1 HCl / HNO3 - heating may be required.); Organic based (dry ash at 450°C and dissolve ash in HNO3 or acid digestion with conc. hot Sulphuric acid adding hydrogen peroxide carefully dropwise until clear).
