Operando kinetics of hydrogen evolution and elemental dissolution I: The dissolution of galvanized steel in hydrochloric acid
نویسندگان
چکیده
A new approach to the simultaneous measurement of hydrogen evolution reaction (HER) and elemental dissolution rates is presented applied galvanized steel coatings with HCl solution. Dissolution profiles revealed several kinetic regimes including intact coating, nanometric Fe2Al5 intermetallic layer, corrosion substrate. The HER Zn were in excellent agreement, quantities interfacial Fe Al consistent predicted 50 nm thick film, demonstrating analytical capabilities atomic emission spectroelectrochemistry (AESEC) technique.

DISSOLUTION KINETICS OF MANGANESE DIOXIDE ORE IN SULFURIC ACID IN THE PRESENCE OF FERROUS ION
Abstract: In this paper, kinetics of reductive leaching of manganese dioxide ore by ferrous ion in sulfuric acid media has been examined. Experimental results show that increasing temperature from 20 to 60 °C and decreasing ore particle size from −16+20 to −60+100 mesh considerably enhance both the dissolution rate and efficiency. Molar ratios of Fe2+/MnO2 and H2SO4/MnO2 in excess to the st...
متن کاملThe effect of absorbed hydrogen on the dissolution of steel
Atomic hydrogen (H) was introduced into steel (AISI 1018 mild steel) by controlled cathodic pre-charging. The resultant steel sample, comprising about 1 ppmw diffusible H, and a reference uncharged sample, were studied using atomic emission spectroelectrochemistry (AESEC). AESEC involved potentiodynamic polarisation in a flowing non-passivating electrolyte (0.6 M NaCl, pH 1.95) with real time r...

Abstract The effect of mechanical activation using an attrition mill on the particle size of an ilmenite concentrate and its effect on the ability of the concentrate for Iron separation during hydrochloric acid leaching and the kinetics of the dissolution process have been investigated. It was observed that mechanical activation in an attritor significantly enhances the dissolution of iron ...
متن کاملDissolution Kinetics of Western Deseret Phosphate Rocks, Abu Tartur with Hydrochloric Acid
The dissolution kinetics of the Abu-Tartur phosphate rock using dilute hydrochloric acid has been investigated. The influence of acid concentration, liquid/solid ratio, particle size and temperature was studied to explore the dissolution kinetics of phosphate rock. It was found that the leaching rate increases with increasing the acid concentration, liquid/solid ratio, temperature and decreases...
متن کاملRole of Calcium Content in Dissolution Kinetics of Iranian Borate Minerals in Sulfuric Acid
The dissolution kinetics of pandermite and hydroboracite, present in an Iranian borate ore, in sulfuric acid has been comparatively studied. The effect of particle size, temperature, and acid concentration on their dissolution rate was investigated. Dissolution rates of both minerals increased by reducing the particle size and by raising the temperature. Although, an increase in the acid concen...
