Resumo: The inhibition efficiency (IE) of an aqueous extract of beet root (BR) in controlling corrosion of carbon steel in well water in the absence and presence of Zn2+ has been evaluated by mass loss method. The formulation consisting of 4 mL of BR extract and 50 ppm Zn2+ offers 98% inhibition efficiency to carbon steel immersed in well water. A synergistic effect exists between BR extract and Zn2+. Addition of N-Cetyl-N,N,N - trimethylammonium bromide (CTAB) does not change the excellent inhibition efficiency of the BR - Zn2+ system. The BR - Zn2+ system shows excellent IE up to 7 days. Polarization study reveals that this formulation controls the cathodic reaction predominantly. AC impedance spectra reveal that a protective film is formed on the metal surface. FTIR spectra reveal that the protective film consists of Fe2+ - betanin complex and Zn(OH)2. The film is found to be UV - fluorescent.
