摘要：The Inhibition efficiency (IE) of various concentrations of a SM(Sodium molybdate)-Zn2+-Aloe verasystem in controlling corrosion of mild steel immersed in well water was evaluated by a weight–loss study. Theformulation consisting of 100 ppm of SM and 25 ppm of Zn2+ and 10ml of aloe vera extract showed 97% IE. Asynergistic effect was noticed between SM-Zn2+-Aloe vera system. In the presence of aloe vera, SM-Zn2+ system hasexcellent inhibition efficiency. Polarization studies reveal that SM-Zn2+-Aloe vera system functions as a anodicinhibitor. AC impedance spectra suggest that a protective film is formed on the metal surface. FTIR spectra reveal thatthe protective film consists of Fe2+-SM complex and Fe2+-Aloe vera complex and Zn(OH)2.
