Extracting chromium (III) from aqueous solutions with 2-ethylhexyl acid phosphate. |
摘要 |
<p>@ This invention concerns a process for extracting chromium (III) from an aqueous solution containing chromium (III) with an extractant comprising a mixture of mono-2-ethylhexyl phosphoric acid and di-2-ethylhexyl phosphoric acid. An organic solvent such as a low aromatic kerosene is employed in this invention for dilution and dissolution of the extractant. Aqueous acid waste streams containing chromium (III) can be reduced to a chromium (III) concentration of 80 ppm thereby enabling the stream to be reclaimed.</p> |
