Abstract
Disclosed is a method of removing a soluble antimony compound from a liquid in which it is dissolved. The liquid is contacted with a hydrated compound, particularly a hydrated compound that forms carbonate ions, bicarbonate ions, or both in the liquid, such as carbonic acid or hydrates of sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, ammonium carbonate, or ammonium bicarbonate. An antimony compound is formed that is insoluble in the liquid and it is separated from the liquid.
