ABSTRACT: Corrosion inhibition characteristics of two biomass
derived extracts from outer leaves of Brassica
oleracea (BO) and Citrus paradise mesocarps
(CPM) on pipeline steel were investigated using modified gravimetric method at
ambient temperature (28 ± °C). Petroleum
pipeline water was used to simulate a pseudo-anaerobic corrosion cell. The
result obtained showed that corrosion was a continuous process in the closed
system, while BO and CPM showed near equivalence corrosion inhibition
efficiency of 91.45% and 89.44% respectively at the concentrations studied. The
thermodynamic data suggests inhibition to be through molecular adsorption on
metal surface.
