Abstract

An extraction system based on polyethylene glycol 1500 and sodium sulfate for extracting lactic acid from aqueous solutions is proposed. The influence of the extraction time, the initial concentration of lactic acid, the molecular weight of the polymer, and the content of the polymer and sodium sulfate in the system on the extraction of lactic acid is investigated. Based on the experimental data, the possibility of isolating lactic acid from fermentation solutions using the proposed environmentally friendly extraction system is shown.
