Abstract

This paper suggests a mechanism of solution and passivation of iron in neutral solution in the presence of a surface oxide. The influence of sodium tungstate on these processes is discussed and it is shown that the oxyanion WO/sup 2 -//sub 4/ possesses electron-acceptor properties. Using the photoelectric data the authors make an estimate of the quantity of tungstate ion adsorbed on the oxide surface for a protective concentration of the inhibitors. If the centers of preferential adsorption are anion vacancies, the minimal quantity of adsorbed tungstate giving complete protection corresponds to the initial concentration of vacancies in the absence of the inhibitor.

A CATALYTIC MECHANISM OF ANODIC INHIBITION IN METALLIC CORROSION

Journal Article Huddle, R; Anderson, P - Advances in Catalysis

It is well known that quite low concentrations of certain oxygen- containing anions, such as chromate, are effective inhibitors of aqueous corrosion of a number of metals. These results have bcen ascribed to specific adsorption of the inhibitor at anodic sites of the metal surface, or alternatively to continuous repair of the protcctivc film. Work on the corrosion of aluminum has suggested that its resistance is largely dependent on the structure of the film; thus, complete passivity is considcred to be associated with the formation of an oxide, while a hydrated oxide or hydroxide film only confers partial protection.

The preparation of WO sub 3 /TiO sub 2 and WO sub 3 /Al sub 2 O sub 3 and characterization by temperature-programmed reduction

Journal Article Vermaire, D; van Berge, P - Journal of Catalysis; (USA)

An equilibrium adsorption technique was used to prepare WO{sub 3}/TiO{sub 2} and WO{sub 3}/Al{sub 2}O{sub 3} samples. The tungsten loading could be controlled by varying the pH and concentration of the aqueous solutions. For both supports there was a definite maximum to the amount of tungsten that adsorbed spontaneously, viz. 988 {+-} 21 and 669 {+-} 19 {mu}mol per 100 m{sup 2} for alumina and titania, respectively. The hydroxyl group to tungsten ratio was 2:1 on alumina for a fully hydroxylated surface. On titania the ratio was 1:1, based on the reacting hydroxyl group density. These stoichiometries point to amore »« less

Inhibition of corrosion of Al 6061, aluminum, and an aluminum-copper alloy in chloride-free aqueous media. Part 2: Behavior in basic solutions

Journal Article Al-Kharafi, F; Badawy, W - Corrosion

Electrochemical characteristics of Al 6061 (UNS A96061), Al and an Al-Cu alloy were investigated in aqueous solutions. Inhibition of the corrosion processes in basic solutions was studied using electrochemical impedance spectroscopy (EIS) and polarization techniques. Among a series of inhibitors, molybdate (MoO{sub 4}{sup 2{minus}}) and dichromates (Cr{sub 2}O{sub 7}{sup 2{minus}}) were found effective in passivating the metal or alloy surface. The high inhibition action of Cr{sub 2}O{sub 7}{sup 2{minus}} was traced and discussed. X-ray photoelectron spectroscopy (XPS) of the different electrode materials revealed the presence of Cu peaks on the Al-Cu alloy surface. Immersion of the different electrodes in basicmore »« less

Inhibition of mercury methylation in anoxic freshwater sediment by group VI anions

Journal Article Chen, Y; Miller, G; Bonzongo, J; ... - Environmental Toxicology and Chemistry

The addition of group VI anions to sediment slurries resulted in the inhibition of the rate of mercury (Hg) methylation. The ranking of inhibition is as follows: tellurate (TeO{sub 4}{sup 2{minus}}) > selenate (SeO{sub 4}{sup 2{minus}}) > molybdate (MoO{sub 4}{sup 2{minus}}) > tungstate (WO{sub 4}{sup 2{minus}}). In sediment slurries treated with TeO{sub 4}{sup 2{minus}} and Se{sub 4}{sup 2{minus}}, methylmercury (MeHg) formation was significantly inhibited (p < 0.05) at the concentrations >50 nM of TeO{sub 4}{sup 2{minus}} and >270 nM of SeO{sub 4}{sup 2{minus}}, while the significant inhibition (p < 0.05) of Hg-methylation by MoO{sub 4}{sup 2{minus}} and WO{sub 4}{sup 2{minus}}more »« less

Growth and Dissolution of Iron and Manganese Oxide Films

Technical Report Martin, Scot

Growth and dissolution of Fe and Mn oxide films are key regulators of the fate and transport of heavy metals in the environment, especially during changing seasonal conditions of pH and dissolved oxygen. The Fe and Mn are present at much higher concentrations than the heavy metals, and, when Fe and Mn precipitate as oxide films, heavy metals surface adsorb or co-precipitate and are thus essentially immobilized. Conversely, when the Fe and Mn oxide films dissolve, the heavy metals are released to aqueous solution and are thus mobilized for transport. Therefore, understanding the dynamics and properties of Fe and Mnmore »« less
