ABSTRACT

The inhibition efficiency of an aqueous extract of beetroot in controlling corrosion of mild steel immersed in well water has been evaluated by weight loss method.10 ml of beetroot extract offers 95% corrosion inhibition efficiency. Polarization study reveals that beetroot extract functions as mixed type of inhibitor. The protective film is found to be uv- fluorescent. The film consists of iron betanin complex as confirmed by fluorescence spectrum.


Keywords: Green inhibitor, beet root extract, mild steel, fluorescence spectra, betanin
