Fertilizer solutions and wet-process phosphoric acid (WPA) contain heavy metal impurities such as arsenic, cadmium, zinc, mercury, lead, copper, manganese, and chromium. Trisodium trithiocyanuric acid, sodium trithiocarbonate, and sodium polythiocarbonate were evaluated as precipitating agents for heavy metals in a 10-34-0 (N-P[sub 2]O[sub 5]-K[sub 2]O) grade fertilizer solution and WPA. A water-insoluble starch xanthate was also evaluated as an adsorbent for the heavy metals in 10-34-0 and WPA.
