Abstract
The sulphuric acid mist released during plate formation process of Automotive Lead Acid Battery manufacturing Industry is a major concern to environmental sustainability and there is a strong environmental drive to control its emission into the work environment. The present work is mainly aimed to reduce the acid mist emission at source itself without affecting the product performance. A “simple and salient” method to reduce the acid mist was carried out using an organic surfactant namely, “Sodium Lauryl Sulphate (SLS)” as an additive to the acid electrolyte. The best method of adding SLS into the electrolyte is by adding it to the required volume of electrolyte that was already filled. After addition of SLS, batteries are subjected to regular formation process. It is noteworthy that acid mist was noticeably reduced i.e. as high as 40% with the addition of SLS to the electrolyte. The study reveal that SLS is a cost effective and viable technique for acid mist reduction and therefore by making manufacturing of Automotive Lead Acid Batteries system in compliance with OSHA's regulations.
