“…There is also evidence via the preferred orientation effects and the impact on the charge transfer resistance (as well as previous literatures [31,32]) that both NTA and NTMP have an affinity for the stainless steel electrode.…”

“…This hypothesis is supported by the crystallization work on NTA that shows as the concentration of NTA is increased, the particle size of barium sulfate precipitated is decreased [23]. The preferred orientation effects by NTMP are also supported by literature that shows both carboxylate and phosphonate molecules are known to adsorb onto stainless steel [31,32]. Thus, when inhibitor molecules are present, a three-way equilibrium is established whereby some inhibitor molecules are in solution, some on the barium sulfate particles and some are on the electrode surface.…”

This paper investigates the influence of barium sulfate scaling and scaling inhibitors on the electrochemical behaviour of stainless steel. The results of a synchrotron radiation grazing incidence X-ray diffraction (SR-GIXRD) and electrochemical impedance spectroscopy (EIS) study on stainless steel shows that different scaling inhibitors interact uniquely with the substrate when barium sulfate is precipitated on the electrode surface. The main effect of the substrate in the presence of inhibitor is a tendency to form smaller barium sulfate particles. The SR-GIXRD patterns obtained in the presence of the two inhibitors were different to each other and to the control, with the carboxylate showing greater amounts of barite solids precipitated together with iron(III) and (II) sulfate, while the phosphonate showed low amounts of barite solid were precipitated. The presence of iron sulfates on the electrode surface as detected by SR-GIXRD, in the case of NTA, suggests that scaling inhibitors are not always benign, and can promote the dissolution of iron species from the substrate. #

“…The importance of functional dissociative groups such as carboxyl and amino groups has been noted [10][11][12][13][14]20]. In a previous paper [2], we reported on the adsorption of various carboxylic acids on the surface of SUS316L stainless steel (S6L) and showed a relationship between the number of carboxyl groups and the adsorption characteristics. Namely, carboxylic acids having two or more carboxyl groups are adsorbed onto surfaces in both reversible and irreversible manners and the extent of irreversible adsorption increases with the increasing number of carboxyl groups and with decreasing pH in the range studied.…”

“…On the other hand, adsorption characteristics of proteins are important relative to the performance of immobilized enzymes, biosensors, and enzyme-linked immunoadsorbent assays [1]. Thus, considerable interest has developed in the adsorption of various organic substances onto solid surfaces [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].

The interaction of polypeptides and proteins with an inorganic surface is intrinsically dependent on the interfacial behavior of amino acids and sensitive to solution conditions such as pH, ion type, and salt concentration. A faithful description of amino-acid adsorption remains a theoretical challenge from a molecular perspective due to the strong coupling of local thermodynamic nonideality and inhomogeneous ionization of both the adsorbate and substrate. Building upon a recently developed coarse-grained model for natural amino acids in bulk electrolyte solutions, here we report a molecular theory to predict amino-acid adsorption on ionizable inorganic surfaces over a broad range of solution conditions. In addition to describing the coupled ionization of amino acids and the underlying surface, the thermodynamic model is able to account for both physical binding and surface associations such as hydrogen bonding or bidentate coordination. It is applicable to all types of natural amino acids regardless of the solution pH, salt type and concentration. The theoretical predictions have been validated by extensive comparison with experimental data for the adsorption of acidic, basic, and neutral amino acids at rutile (α-TiO 2 ) surfaces.
