Process for removing heavy metal ions and arsenic from wet-processed phosphoric acid |
| abstract |
PROCESS FOR REMOVING HEAVY METAL IONS AND ARSENIC FROM WET-PROCESSED PHOSPHORIC ACID ABSTRACT OF THE DISCLOSURE The disclosure relates to a process for removing heavy metal ions and arsenic from wet-processed phosphoric acid, wherein the crude wet processed phosphoric acid is treated at temperatures between 10 and 100°C initially with a di-organyldithiophosphoric acid ester and then with an adsor-bent, and the phosphoric acid so purified is separated from the ester and adsorbent. More particularly, the wet-processed phosphoric acid is treated with the diorganyldithiophosphoric acid ester at temperatures higher than 50°C and with the ad-sorbent at temperatures lower than 50°C. |
