Potentiodynamic polarization (PDP) and Fourier transform infrared spectroscopy techniques were used to explore the corrosion inhibition properties of ethanolic extracts derived from Nymphaea lotus L and Aloe barbadensis plants on mild steel immersed in a 1M H2SO4 solution. The compilation of the inhibition performance calculated using PDP method under various conditions was extensively outlined. The Plant extract has shown an effective inhibiting behaviour, with results of up to 80% and 77% for water lily and aloe vera respectively. The concentration of the extracts increased with the inhibitory efficiency. It was shown that the extracts had anodic and cathodic polarisation effects, acting as mixed inhibitors. The results of the study show that in acidic settings, extracts from water lilies and aloe vera can effectively and environmentally protect mild steel from corrosion.
