A GREEN CHEMICAL FOR THE MICROBIAL ACTION AND INHIBITION OF CORROSION OF CARBON STEEL IN CHLORIDE ION ENVIRONMENT

J. Yamuna, Noreen Antony

The aim of the present work is to study the inhibition efficiencies of the green biocide namely benzyl triethyl ammonium chloride (BTAC) in the presence and absence of various inhibitor systems carboxy methyl cellulose–Zn2+, caffeine–Zn2+, polyvinyl alcohol–Zn2+, sodium meta silicate–Zn2+ in 60 ppm of chloride ion solution. Classical weight loss method and FTIR spectroscopic technique are adopted. BTAC shows synergistic effect with CMC, PVA and SMS–Zn2+ systems at low concentrations while caffeine–Zn2+shows antagonistic effect with BTAC at all concentrations. FTIR spectra do not show any characteristic peaks for BTAC and BTAC reacts only with electrolyte and is responsible for the change in environment thereby changing the mechanism of electrode reaction.
