| titleOfInvention | METHOD FOR THE ELIMINATION OF CHROME FROM LIQUID EFFLUENTS AND THEIR RECOVERY. |
| abstract | METHOD FOR THE ELIMINATION OF CHROME FROM LIQUID EFFLUENTS AND THEIR RECOVERY. IT INCLUDES TREATING THE EFFLUENT WITH AN EXTRACTING AGENT, PRIMENE 81R, IN AN ORGANIC SOLUTION (SOLVENT, CHEROSENE OR OIL). THE AQUEOUS DISSOLUTION IS FREE OF CHROME AND IS POSSIBLE TO SPILL AFTER THE CORRECTION OF THE PH, IF NECESSARY. CHROME IS REMOVED FROM THE ORGANIC PHASE THROUGH AN ALKALINE DISSOLUTION, PRODUCING A REGENERATED ORGANIC PHASE AND A WATER SUSPENSION OF CHROME (III) HYDROXIDE. THE REGENERATED ORGANIC PHASE IS RECIRCULATED AT THE HEAD OF PROCESS. FROM THE AQUEOUS SUSPENSION A CHROME (III) HYDROXIDE SLUDGE IS OBTAINED BY FILTRATION. ENVIRONMENTAL APPLICATION IN THE FIELD OF DEPURATION OF INDUSTRIAL EFFLUENTS CONTAMINATED WITH CHROME. |
