Abstract
The determination of microamounts of fluorine in the existence of aluminum has been done by the photometric method with alfusone. The solution of AlF63- complex ions was made alkaline (Ph>12), and the liberated aluminum was removed by an extraction with oxine-chloroform. As small amounts of chloroform and oxine remained in the aqueous layer, chloroform was removed by heating. The solubility of oxine became minimum by making pH 8 when it was extracted, and its color could be minimized by increasing the amount of alfusone to be added. Less than 504 μg of fluorine in the presence of 20 μg of aluminum was satisfactorily determined by this procedure.
