Disposal of Waste Battery Electrolyte by Neutralization, Precipitation and Decantation Process on Industrial Scale

Abstract

The battery electrolyte which contain heavy metals such as lead, zinc are neutralized by adding sodium hydroxide and depending upon cumulative concentration of lead and zinc and other heavy metals ; sulphide ions are introduced equal to cumulative concentration of all lead and zinc and other heavy metals. The lead, zinc and other heavy metals form metal sulphide which are generally very insoluble and gets precipitated which can be very easily removed by settling them at bottom and followed by decantation process.
