Rhizophora apiculata Extract as Corrosion Inhibitor in 3.5% NaCl for API 5L Steel
The corrosion inhibition efficiency of Rhizophora acipulata(RA) extract was investigated for API 5L Steel corrosion in 3.5% NaCl using weight loss and polarization method. Fourier Transform Infra-Red (FTIR) was used toanalyze the characteristics of extract RA functional groups. The weight loss and polarization result indicated that extract RA inhibited API 5L steel corrosion rate. Based on the polarization result, the inhibition efficiency reached up 97.52% with addition 100ppm of RA extract.
