Procedure
The composition was calcined at 1000° C. for about 3 hours to obtain 15.5 g of black product (Ba:77%). The crushed black product and 10.0 g of barium carbonate were dissolved in pure phosphoric acid to obtain 315 g of barium salt-phosphoric acid mixture (H3PO4 :50%; Ba:6.00%). A 205.0 g sample of the barium salt-phosphoric acid mixture was added to 1000 g of the extracted phosphoric acid of Example 1 to treat it under the same conditions. The product was treated with the powdery active carbon to obtain substantially the same results of Example 1.
