Abstract

Corrosion of mild steel in HCl was investigated using the weight loss method. The mild steel used was cut into 16 coupons with 5.0 cm x 5.0 cm x 0.2 cm dimensions which weredegreased with ethanol and washed with distilled water and finally weighed. The mild steel coupons were exposed to HCl with varied concentrations (0, 10, 25 and 40%) of Garcinia kola extracts used as corrosion inhibitors for 4 hours at 400C and 600C respectively. The result showed that at 400C; the inhibition efficiency of 65.5% was observed at 25 % HCl concentration and 62.9% at 40% HCl concentration while at 600C; inhibition efficiency of 87.7% was at 25% HCl concentration and 88.1% at 40% concentration respectively. It can be concluded that increase in concentration increases the inhibition efficiency. The presence of flavonoid and alkanoids in bitter kola stem is a good inhibitor
