Corrosion Inhibition Study of Proguanil Hydrochloride for Mild Steel Corrosion in 2.0 M HCl by Weight Loss Method

This study considers proguanil hydrochloride for inhibition of mild steel corrosion in 2.0M HCl by weight loss method. Useful parameters like mean Corrosion Rate (XCR), Percentage Inhibition Efficiency (%IE) and degree of Surface Coverage (q) were evaluated from raw data generated experimentally. Analysis of generated data and available literature show that; XCR decreased in the present of proguanil hydrochloride inhibitor. The decrease in XCR increased with increased in inhibitor concentration but tested non-significant (P<0.05) for all inhibitor concentrations while showing continuous appreciation to values approaching significance level at high (5.0 x 10-4M) inhibitor concentrations and low (303K and 313K) corrodent temperatures. Useful parameters (%IE and q) increased with increase in inhibitor concentration and decreased with rise in corrodent temperature.
