Creation and study of formulations as inhibitors of metal corrosion and scaling for stabilization water treatment in water utilization systems (a review)

“…Simultaneously, studies of the molecular structure of ZnHEDP still continue. New data on the structure of the complex obtained from XPS data were compared to known [4][5][6] absorption IR spectra of the complex [7]. Based on the results [7], it was found that upon coordination of a phosphonic group by Zn(II), the localized PO π-bond remains unchanged, there is no third order symmetry axis of the phosphonic group, and Zn(II) in the complex occupies positions with different types of coordination by phosphonic groups: intermolecular (I) and intramolecular (II).…”
