Palm oil based emulsion liquid membrane formulation for succinic acid extraction performance

Emulsion liquid membrane (ELM) process has received significant attention due to its simple operation and high selectivity to the target solute. One of the potential applications of ELM is in the separation and purification of succinic acid from fermentation process. The most important aspects for a...
