Recovery of heavy metals from aq. effluents
Process for recovering heavy metals contained in aq. effluents using a polymer (I) / complexing agent (II) system in which the (I) is chosen from opt. substd. polyaniline, opt. substd. poly(paraphenylene-vinylidene), opt. substd. poly p-phenylenes, opt. substd. polyfuran and opt. substd. polypyrrole...

| description | Process for recovering heavy metals contained in aq. effluents using a polymer (I) / complexing agent (II) system in which the (I) is chosen from opt. substd. polyaniline, opt. substd. poly(paraphenylene-vinylidene), opt. substd. poly p-phenylenes, opt. substd. polyfuran and opt. substd. polypyrrole, and the (II) is chosen from ethylenediamine, 1,10-phenanthroline, triaminotriethylamine, triethylenetriamine, tetraethylenepentamine, glycine, ethylenediaminetetraacetic acid (EDTA), ethylene glycol bis ( beta aminoethyl-ether) N,N-tetraacetic acid (EGTA) and dimethyl glyoxime (DSM).
L'invention concerne un procédé de récupération des métaux contenus dans les effluents aqueux par fixation sur une colonne d'échange 1 suivie d'une étape de décomplexation 4 et d'une électrolyse 6. |
