Rubidium Sulfate-Rb2SO4
Rubidium sulfate is an alkali metal sulfate with the chemical formula Rb2SO4.Appearance is a white crystalline powder, soluble in water. Attention: After inadvertent contact with eyes, flush immediately with plenty of water and seek medical advice; wear proper gloves; wear goggles or mask. 25Kg/drum; customized packing specification according to customer’s requirement
Preparation method
Rubidium carbonate is dissolved in water to make a saturated solution, which is slowly added to 20% dilute sulfuric acid until the solution becomes weakly basic. The solution was heated to boiling and filtered to remove insoluble matter. The filtrate will be acidified with sulfuric acid to weakly acidic after evaporation and concentration, concentration to a considerable number of crystals precipitated after cooling, and then drained, and finally dried at 70 ~ 100 ℃.
