Concentrated propionic acid production by electrodialysis

In this study, concentrated propionic acid was obtained by electro-electrodialysis and electrodialysis with bipolar membranes of a fermentation broth. The current efficiency was high but decreased with time, especially with bipolar membranes. The presence of inorganic ions led to the formation of ot...

More Information
Summary:In this study, concentrated propionic acid was obtained by electro-electrodialysis and electrodialysis with bipolar membranes of a fermentation broth. The current efficiency was high but decreased with time, especially with bipolar membranes. The presence of inorganic ions led to the formation of other acids.
