Collaborative Influence of Zinc Oxide and Triethylene Amine on the Corrosion Behavior of Mild Steel in Hydrogen Cyanide Environment
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2006, Vol 5, Issue 9
Abstract
The analysis of the relative contribution of Zinc Oxide/Triethylene Amine mixes in controlling corrosion of mild steel in hydrogen cyanide environment is undertaken in this study. In earlier works [1,2], the individual effects of some organic and inorganic inhibitors were studied using 20ml of three different concentrations (0.5M, 1.0M and 1.5M) of the inhibitors from which diethylene amine from the organic family and zinc oxide from the inorganic family were reported to be very effective. However, in this work, mixes of zinc oxide and triethylene amine in varying volumetric combinations were considered at 1M concentration. The weight losses for the various mixes were very low ranging from 7.7mg to 44.0 mg, superior to the situation observed in [1] and [2]. The corrosion rates followed reducing pattern except for the solution containing 5ml zinc oxide which had a sudden rise from 0.0090 mmpy to 0.0484 mmpy after 168 hrs. The weight loss ratios were in fractions in the range 0.2857 to 0.8361. It is concluded that the mixture of triethylene amine and zinc oxide is effective with increasing volume of amine rather than the individual inorganic or organic inhibitor specie.
