Phosphoric acid is an important mineral acid and commonly manufactured by two routes, thermal and wet process. Wet process phosphoric acid WPA is a more economical and environmental friendly method of phosphoric acid production 1 3 . However, WPA contains various undesirable impurities and must be purified during the downstream production.
