METHOD FOR RECOVERING CATALYST METAL FROM WASTE OF TEREPHTHALIC ACID PRODUCTION |
| 摘要 |
<p>A method for rapidly and environmentally-friendly recovering valuable catalyst metal such as Co, Mn or so on from waste of terephthalic acid production is disclosed. The method comprises the steps of: adjusting pH of the waste of terephthalic acid production to 2.5 to 7; adding NaHCO3 slurry, which is prepared by mixing NaHCO3 and water, into a precipitation reactor, into which the waste of terephthalic acid production is added; heating a mixture of the waste of terephthalic acid production and NaHCO3 slurry; and separating a metal precipitate from the reaction mixture.</p> |
