摘要
it is proposed according to the invention, a continuous process for the removal of organic impuretes and discolouration () of phosphoric acid of wet purification process onlye, which has been purified by organic solvent extraction process in a.debarasse hydrofluoric acid residuel by training and has high temperature steam treated by hydrogen peroxide.the method is characterized in that the mixture in the mixing zone of the wet process phosphoric acid and hydrogen peroxide, so only a temperature of 100200 c, preferably 140 160 c, and we respond to this temperature for 1 to 4 hours.it is a 85 - 90 c phosphoric acid from wet process prior to purify and treat and sent the temperature inside of the air first through a bed of active carbon(f), which is the basis of peat and activity by the steam and provides a surface b of 800 to 1000 m2 / g).and then through a bed of a mixture of silicon carbide and / or graphite and maintains a transmission speed less than 0.5 m3 / h of wet process phosphoric acid of pr m of bed of active carbon
