Description
Application of corrosion inhibitors are the most versatile corrosion prevention methods
of carbon steels in corrosive environments. Research on non-toxic chemical compounds
are ongoing and results from previous study have proven the effectiveness of the
compounds. Data on corrosion inhibition of ginger (GG), tea tree (TR) and grapefruit
(GF) oil extracts on low carbon steel in 0.5 M H2SO4 are presented. The extracts
performed effectively with optimal values of 99.56 %, 98.17 % and 98.32 % at 2.5 %
GG, 3.5 % TR and 3 % GF concentrations. Corresponding corrosion rate values are
0.28 mm/y, 1.16 mm/y and 1.49 mm/y. Corrosion rate at 0 % extract concentration is
63.33 mm/y. Performance of TR extract significantly varies with time and concentration
with statistical value of 48.21 % and 23.02 %. GG and GF concentration where the only
statistically relevant factors for GG and GF performance with statistical values of
68.42 % and 73.20 %. Standard deviation data for GG extracts varied minimally from
mean values compared to TR and GF extracts. Results shows 92 %, 18 % and 63 % of
GG, TR and GF extracts inhibition data are above 95 % inhibition value at margin of
error of 6.99 %, 10 % and 12.19 %.
