PHOSPHORIC acid is the second most produced acid after …….H2SO4. It was used as a raw material for the production of detergents, food products, and alimentary supplies for cattle, toothpastes and fertilizers. High grade phosphoric acid was obtained using liquid-liquid extraction with aliphatic alcohols to separate metal and fluoride ion impurities in the aqueous phase. The influence of alcohol concentration, organic/aqueous phase ratio, temperature, shaking time and phosphoric acid concentration on P2O5 extraction was studied. N-Nonanol proved to be the most efficient and selective alcohol and the temperature had a slight positive effect and the extraction was enhanced by increasing P2O5 and with the increase of organic/aqueous phase ratio. The optimum organic/aqueous phase ratio was determined to be 2.0. Stripping was also investigated, the purification of stripped phosphoric acid was achieved using sodium ethyl xanthate where 95.1% of iron was removed, also aminotrimethylene phosphonic acid can be successfully used for decreasing iron content to 190.9 ppm and to produce highly pure grade phosphoric acid.
