Abstract

Chemical process for the treatment of residual waters of teneria, richs in chrome (III). The residual bath with sodic and/or potassic bicarbonate is alkalinized, and/or diluted caustic sosa, until the redisolution of the chrome precipitate begins. Hidrogen peroxide is added, maintaining the treatment at ambient temperature for 1-3 hours. The ion cromato is then fixed in a strong anionic exchange resin, and finally both the chrome and resin are recovered using an in situ reduction reaction of chromium chrome (III), with hidrogen peroxide in acid medium, which allows eluir the chrome (III) with a minimum of eluyente and use it again like a curing liquor after a basificación. It applies to the residual bathrooms and the water from the pitching and lubrication. (Machine-translation by Google Translate, not legally binding)
