Electrodialysis Production of Hypophosphorous Acid

It is a method of preparing hypophosphorous acid with electrodialysis. It comprises an insoluble anode, an insoluble cathode and an aqueous solution of hypophosphite anions. The direct current, through the insoluble anode to cathode in electrical contact with the aqueous solution to generate H⁺, forms hypophosphorous acid solution. In the paper, we study the best term of different factors about the experiment. The process is simple, low cost and high efficient, It is a cleaner production without waste residue and waste water.
