ABSTRACT:
Any product that has been developed should undergo various tests for standardization before it is put into use by the customers. Numerous plants have been evaluated/investigated as corrosion inhibitors for mild steel in acid medium. In the present study the corrosion inhibitive nature of the acid extract of Tectona Grandis for mild steel in 1M HCl and 0.5M H2SO4 media for standardization of the plant extract was evaluated through gasometric method. The stability and storage condition of the extract was tested using weight loss method. Gasometric method shows decrease in hydrogen gas evaluation with increase in extract concentration showing the inhibitive nature of the extract. The extract in the base HCl was found to be up to 45 days of storage period in room temperature. There is no significant difference in inhibition efficiency exhibited by plant extract stored in room temperature and in refrigerated condition. The mode of inhibition has been explained from the physiochemical constituents present in the extract and FTIR results.
