This study employed a quantitative analysis method to determining the corrosion rate based on weight loss method. It involved exposing the mild steel substrate samples to the corrosive media i.e. 3 % NaCl for different exposure time. The measurement of specimen weight done before and after exposure and measuring the loss of weight of sample to find the corrosion rate as function of time. Then inhibitive effect of o-anisidine with different concentration on corrosion of mild steel in 3% NaCl was investigated. The inhibition performance of o-anisidine results illustrate that o-anisidine act as effective corrosion inhibitor for mild steel in 3% NaCl. It was observed that corrosion inhibition efficiency and corrosion rate obtained from weight loss method increases with increase in concentration of o-anisidine. The Langmuir adsorption plot illustrate the strong adsorption of o-anisidine molecules on the mild steel surface.
