| titleOfInvention | Purification method of monopotassium phosphate |
| abstract | The invention discloses a purification method of monopotassium phosphate. According to the invention, industrial phosphoric acid is filtered by an SBA-15 molecular sieve chelate adsorbent to remove impurity ions and then reacts with potassium chloride, so that purified monopotassium phosphate is collected from reaction products; the main body content of monopotassium phosphate obtained by the purification method disclosed by the invention is larger than 99wt%, and the yield of monopotassium phosphate is more than 90%; and through analysis and detection, the contents of chlorides and metal impurity ions in the product meet the standard of medicinal monopotassium phosphate. In the invention, the SBA-15 molecular sieve is used as a carrier, and the prepared SBA-15 molecular sieve chelate adsorbent has strong adsorption capacity to the metal impurity ions in a raw material industrial phosphoric acid, thereby effectively removing the impurity ions therein; and the purification method has the advantages that reaction process operation is simple, cost is reduced, yield is improved and the obtained product is stable in quality, thus the purification method is suitable for industrial production. |
