Abstract:

The intent of this study is to establish the performance of Caryota Urens leaves extract (CUL) as a corrosion inhibitor on mild steel in citric acid and hydrochloric acid medium by weight loss method of corrosion monitoring. The inhibition efficiency was tested by varying the inhibitor concentration and time of immersion in 1M citric acid and 1M Hydrochloric acid, pH of the bath was also monitored. The results proved the adsorption of the inhibitor on mild steel surface and 2.5% V/V of CUL offered90% and 92% inhibition efficiency for 24 hour immersion at room temperature in Citric acid and Hydrochloric acid respectively. Hence CUL extracts can be used as green inhibitors in citric acid and hydrochloric acid pickling baths for mild steel corrosion mitigation.
