Production of Aldonic Acids by Bipolar Membrane Electrodialysis

Industrial & Engineering Chemistry Research, 2017
Conventional methods for the synthesis of aldonic acids are typically expensive and complex, generate contaminated water, and generally yield a low purity of the products. In this work, the bipolar membrane electrodialysis (BMED) process was used as an environmentally friendly and efficient method to produce aldonic acids (lactobionic acid and gluconic

Citric acid production by electrodialysis with bipolar membranes

Chemical Engineering and Processing: Process Intensification, 2002
Production of citric acid from sodium citrate was carried out by electrodialysis (ED), using bipolar membranes (BP) prepared from poly(phenylene oxide) (PPO). The process feasibility was tested using a laboratory ED-cell with an effective area 20 cm 2 . Based on the configuration of BP-cation membranes (C)-BP, the performances of various sodium sulfate

Mechanisms limiting product concentration in bipolar membrane electrodialysis

Desalination
This study addresses the development of bipolar membrane electrodialysis for sodium hydroxide and acid production from strong electrolyte feeds. We studied three primary mechanisms that limit maximum product concentrations: (1) acid diffusion through anion‐exchange and bipolar membranes, (2) current‐induced membrane discharge in weakly‐acidic cation ...

Bipolar membrane electrodialysis for the alkalinization of ethanolamine salts

Journal of Membrane Science, 2011
Bipolar membrane electrodialysis for the production of organic bases, in contrast to organic acids, has received little attention in the scientific literature. In the present work we have investigated and compared different membrane configurations for the alkalinization of monoethanolamine salts into the organic base monoethanolamine.

Advancements in Bipolar Membrane Electrodialysis Techniques for Carbon Capture

Langmuir
Bipolar membrane electrodialysis (BMED) is a promising technology for the capture of carbon dioxide (CO2) from seawater, offering a sustainable solution to combat climate change. BMED efficiently extracts CO2 while generating valuable byproducts like hydrogen and minerals, contributing to the carbon cycle.

Electrodialysis Pump Based on Enhanced Water Dissociation of Bipolar Membrane

Analytical Chemistry, 2020
We describe a novel micropump mode-electrodialysis pump (EDP), which is based on the recombination of hydrogen and hydroxyl ions generated by enhanced water dissociation of bipolar membrane (BPM). The pump is in a sandwich-like configuration in which the central production channel is spatially isolated from two outer regenerant chambers by a BPM ...

Chapter 3 Bipolar Membrane Electrodialysis

2007
Publisher Summary This chapter provides an overview of the technology of bipolar membrane electrodialysis. The bipolar membrane is a layered membrane constructed so that one surface is a cation exchange layer, while the opposite surface is an anion exchange layer.

Electrodialysis with Bipolar Membranes: Principles, Optimization, and Applications

Russian Journal of Electrochemistry, 2002
This paper is an overview of the bipolar membrane technology. The process of electrodialysis with bipolar membrane (EDBM) along with the different EDBM process configurations are presented. Some ways of optimization of both the bipolar membranes and the EDBM technology are envisaged.

Utilization of Bipolar Membrane Electrodialysis for Salt Water Treatment

Water Environment Research, 2013
ABSTRACT: Bipolar ion‐exchange membranes, using polystyrene ethylene utylenes polystyrene (PSEBS) with polyvinyl alcohol as the intermediate, were fabricated and evaluated for their potential to remove secondary salts from lab‐prepared salt solutions. Experiments were carried out in batch re‐circulation mode.
