solution is obtained by hydrochloric acid leaching antimony oxide, then, sodium potassium tartrate was added to prevent hydrolysis. The aqueous solution of antimony trichloride can be stable at acidic, neutral or basic conditions when the range of molar ratio of sodium potassium tartrate to Sb3+ is 1.7-2.1 and antimony concentration is less than 75.24 g/L. Finally, sodium thioantimonate solution......
