Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H3PO4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. It is a major industrial chemical, being a component of many fertilizers. WebSignificant amounts of foam generated during the production of phosphoric acid would severely occupy the head space in the reactors, thereby reducing output capacity dramatically. Here, we first proposed a green and clean approach based on Fenton oxidation theory to mitigate the generation of foam.
