Rubidium Expanded View

Rubidium

Location:  Group 1, Period 5
Atomic Weight:  85.4678
Coordination Number:  (6)
Chemical Form in Solution:  Pt(Cl)62-
(coordination number in parentheses is assumed, not certain)

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, and HF aqueous matrices. Stable with most metals and inorganic anions. Forms insoluble Rb2[PtCl6] (0.028g/100mL 20aq).

Stability:  2-100 ppb levels stable for months in 1% HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 0.1-1% HNO3 / LDPE container.

Rb Containing Samples (Preparation & Solution):  Metal (dissolves very rapidly in water); Ores (sodium carbonate fusion in Pt0 followed by HCl dissolution - blank levels of Rb in sodium carbonate critical); Organic Matrices (Sulphuric / peroxide digestion or nitric / Sulphuric / perchloric acid decomposition).
