The performance and mechanism of corrosion inhibitions of POCA were studied bymethods such as weight-loss, electrochemistry, EDS, XPS and quantum chemistry. It isfound that POCA is cathodic corrosion inhibitor, having synergistic effect with HEDP andZn~(2+). The P and O atoms of phosphono have important electron density contribution toHOMO orbital and the electron gross orbital population is bigger than 1, so it is easy toform absorbing location between phosphono and metal resulting in good corrosioninhibition on mild steel.
