VERFAHREN ZUR WIEDERGEWINNUNG VON BATTERIESÄURE AUS BLEISÄUREBATTERIEN
摘要
<p>The present invention discloses a process for rejuvenation of strip acid employed in the reclamation of expended lead-acid battery acid through extraction and filtration for removing metallic impurities from the battery acid. In the process of removing impurities from battery acid through extraction, the extractant becomes loaded with impurities and loses its effectiveness. Extractant may be regenerated by contacting it with an strip acid. In the present invention, a reduction process is employed to regenerate the strip acid so that it may be used repeatedly. By recycling the extractant and the strip acid in the present invention, the present process further increases the effectiveness of battery acid regeneration-producing a reclaimed battery acid fluid which performs very well in new batteries and substantially reducing by-product waste in the regeneration of the battery acid.</p>
