Double emulsion (water-in-oil-in-water) system in succinic acid extraction - A stability study

Emulsion liquid membrane (ELM) process is a very promising method for the industrial separation process. This system offers many advantages, including simple operation, high selectivity, low energy requirement, and simultaneous step of extraction and stripping process. One of the most important aspe...
