“…This can be explained as that the reduction of oxygen to OH − is the domain cathodic reaction in the alkalescent buffer solution for steel rebar corrosion. According to the literature [51], IP6 exists in the form of phytate irons (C 6 H 6 (H 6 P 6 O 24 ) 6 − and (C 6 6.

“…According to our knowledge only Torres et al [24] applied cyclic voltammetry (CV) on the glassy carbon and gold electrode for the evaluation of the Fe(III)/Fe(II) redox response in the presence of phytate. Natural occurrence of phytic acid, its complexation ability, and adsorptive properties are promising for the inhibition of corrosion processes, therefore numerous electrochemical studies of the corrosion inhibition effect of phytates are reported recently [33][34][35][36]. In a series of publications Marken and coworkers published electrochemical characterization of layer-by-layer (LBL) assembled iron phytate films [11,37,38].…”

“…It is easy to see that the efficiency of the PhA itself in this estimation is 3 times lower, but it is indisputable that the modification of the phytate CC, especially of that formed in the presence of Mn 2+ , significantly enhances the protection of galvanized steel. In [72], the effect of the solution pH on the mode of binding between PhA and the Fe surface was studied. In was found that PhA can affect the corrosion behavior of Fe in different ways.…”

This article continues the review of studies (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016) dealing with the passivation of various metals by solutions of organic corrosion inhibitors. It provides an overview of papers on the passivating properties of organophosphates, their complexes and salts. The results of corrosion and electrochemical studies, as well as studies on the composition and structural features of surface layers on metals by a variety of physicochemical methods are considered. Organic phosphorus compounds are often called organophosphates, especially in the case of pesticides and even toxic agents. Of course, it is unlikely that such materials have application prospects for the inhibition of metal corrosion. That is why in this series of reviews we consider organophosphates in a narrower sense limited to phosphoric acid esters and their salts, as well as phosphonic acids, their salts or complex compounds with metal cations [1][2][3][4]. The easy synthesis of acid esters of phosphoric acid, the stability of mono-and disubstituted ester anions, their ability to form complexes and hydrophobic passive films on oxidized metal surfaces has been known for a long time [1]. They can be used for the passivation of phosphated metal surfaces, and their salts with amines are used within deicing formulations. These salts can inhibit not only corrosion but also formation of deposits, so they are used in two-phase systems in the oil industry. Since higher homologues are more effective, the solubility of alkylphosphonic acids is commonly increased by ethoxylation. Salts of these acids are used in cooling lubricants, e.g., waterbased cutting fluids. The low toxicity, ability to be chemisorbed on a metal surface, and some useful technological properties of acid esters of phosphoric acid continue to motivate researchers to look for effective corrosion inhibitors of various metals among these compounds and to study their protection mechanisms [5][6][7][8][9][10][11][12][13][14]. Key words: metal corrosion, inhibitors, metal passivation, organophosphates.
