The Inhibitive Effect of Gnetum africanum, Gongronema latifolium and Chromolena odaratum Extracts on Corrosion of Stainless Steel in 1 M HCl and H2SO4 Solutions

Full Text PDF


Extract of various plants; Okazi leaf (Gnetum africanum), Utazi leaf (Gongronema latifolium) and Elizabeth leaf (Chromolena odaratum) was investigated as corrosion inhibitor of stainless steel in 1M HCL and H2SO4 using conventional weight loss. Results were obtained at intervals of 24, 48, 72 and 96 hours respectively. The corrosion rate and inhibition efficiency were calculated. The results revealed that all the plant extract act as inhibitors in the acid environments while Elizabeth leaf (Chromolena odaratum) proved to be better corrosion inhibitor than Okazi plant (Gnetum africanum) and Utazi plant (Gongronema latifolium) extract as it recorded the highest inhibition efficiency of 90.95% in 1M HCL for 20 ml concentration.
