Abstract

PURPOSE: To completely remove organic matter in extracted phosphoric acid whose concentration of H3PO4 is maintained at high level by contacting the phosphoric acid with chlorate at relatively low temperature and reducing the remaining chlorate so as to obtain phosphoric acid which will not be colored by heating after the treatment.
