Extraction of Fumaric Acid from Aqueous Solution

In order to recover fumaric acid from aqueous solution, severalextractants for the extraction of fumaric acid were examinedpractically. It was found that the phosphorus-bonded oxygen-donorextractant TRPO was the most effective and economical one in the seextractants.For practical application, many factors affecting the extraction and stripping were considered, a new process of recovering fumaric acid from aqueous solution was proposed.
