CHROMATE REMOVAL FROM CONCENTRATED CHLORATE SOLUTION BY CHEMICAL PRECIPITATION |
摘要 |
<p>A method has been devised for removing hexavalent chromium from concentrated aqueous alkali metal chlorate solution by reacting the solution with an inorganic sulfur containing compound and separating divalent and trivalent chromium compounds from the solution. Alkali metal hypohalites may be simultaneously removed from the chlorate solution by reaction with excess inorganic sulfur containing compound.</p> |
