Abstract

Inhibition of corrosion of mild steel in 1 M hydrochloric acid solution by Ammonium pyrrolidene dithiocarbamate (APDe) was evaluated using weight loss, polarisation and electrochemical impedance techniclues. Uesults obtained through the above mentioned techniques indicated that inhibition efl"iciency (IE) increased with concentration of inhibitor, thus reaching a maximum efficiency of 95% at 1 x to-I M. The rise in temperature did not alter the corrosion rate of mild steel drastically at higher inhibitor concentration. The adsorption of inhibition followed Langmuir isotherm. TIle activation energies generally increased with concentration revealing chemisorption of inhibitor on the mild steel surface. Surface analysis by XRD and {IV-luminescence emission spectra were also carried out to establish the mechanism of corrosion inhibition.
