Abstract

The main aim of this current research work is to examine about the “Emulsion Liquid Membrane” (ELM) stability via membrane breakage (%) for lactic acid (LA) extraction from the feed phase. This research article mainly discusses about the detailed experimental study of the various process parameters affecting the membrane breakage and its performance. The ELM formulation is done by using organic phase constituents containing extractant (tri-octylamine (TOA)), diluents i.e., hexane and surfactant Span 80), and internal phase (0.1 M sodium carbonate solution). The optimal numbers of several process variables for gaining a stable ELM are as follows: emulsification time: 20 min, emulsification speed: 2000 rpm, span 80 concentrations: 4% (v/v), internal phase concentration: 0.1 [M], extractant (TOA) concentration: 10%, phase ratio: 1.0 (v/v), treat ratio: 2 (v/v), and stirring speed: 200 rpm. The percentage (%) lactic acid efficiency stripped into the ELM with the lowest membrane breakage of 4.5 % was found 95 %. Overall, the findings of this research related to ELM formulation having good stability suggest that this ELM based technology for lactic acid extraction from aqueous feed phase has great potential.
