A Cocoa pod shell is waste that can be used as an organic inhibitor. Cocoa pod skin contains tannins which are raw materials in the manufacture of organic inhibitors. The reason for this research is to ascertain whether cocoa pod extract can influence the rate at which iron nails corrode in a medium containing a 3% NaCl solution. The concentrations of cocoa pod extract utilized were 1%, 2%, 4%, 8%, 16%, and 32%. The results showed that a 3% NaCl medium had the best corrosion rate, namely at a concentration of 16% with a corrosion rate of 0.7038x10-6 g/cm². hour and an inhibition efficiency of 81%. In contrast, the corrosion rate in saltwater is 0.8504 x 10-6 g/cm² hour and the inhibition efficiency is 63% at a concentration of 4%. According to the study's findings, cocoa shell extract was found to be more efficient against nail erosion at a higher concentration. [ABSTRACT FROM AUTHOR] |
