Voacanga Africana as a Green Corrosion Inhibitor on Concrete Sewers

William-Porbeni, D. Ogbereyo, S. Gumus, R. H. Tuaweri, T.J

Abstract

This study investigated the inhibition of microbial concrete degradation mediated by acidithiobacillus thiooxidans in sewer wastewater using Voacanga Africana leaf extracts as an inhibitor. concrete samples were subjected to biogenic sulfuric acid corrosion in sewer wastewater for 26 months, the corroded concreted cubes were thereafter coated with plant extracts and subjected to sewer water for a further 5 weeks. Variations in weight loss, pH, and sulfate concentration were used to evaluate the effects of plant extracts on biogenic sulfuric acid corrosion of the coated concrete samples. The decline in SOB population, concentration, and formation of corrosion by-products were recorded. Recorded corrosion rates before coating was between 0.343364mpy - 1.323614 mpy. Qualitative analysis of the ethanolic extracts was positive for the presence of tannins, saponins, flavonoids, alkaloids, and terpenoids found in plant tissues with the absence of cardiac glycosides. GC-MS study of Voacanga Africana ethanolic extracts revealed the presence of 83 components. The major constituents were identified as; Thymol, Phenol, Pentanoic acid, and Eugenol. Biocorrosion control determined the effects of extracts on concrete corrosion in sewer waters. A marked decline in the rates of corrosion with extract coating was recorded for coated concretes (0.001486mpy - 0.002622mpy). An increase in inhibition efficiency with an increase in extract concentration was observed and was in the range of 68% ? 72%. X-ray diffractive analysis and scanning electron microscopy showed morphological variations in concrete before and after coating.
