摘要: The inhibiting effects of Gongronema latifolium on corrosion aluminum in 0.5M and 2M HCl solution was investigated using gravimetric technique at temperatures 303K 333K. results indicated that the extracts inhibited process acid media inhibition efficiency improved with inhibitor concentration but decreased increase temperature which suggests a physical adsorption. analysis showed linear quadratic variables were highly significant, as well as, interaction effect time. optimum conditions obtained were, Acid Concentration 1.73mol/l; Temperature 328.62 K; Time 10.14 hours; Extract 1000mg/L; Optimum Inhibition Efficiency this condition predicted to be 74.14%. Gravimetric experiments carried out these validate values. experimental value 75.43% agreed closely from regression model. This study has revealed (GL) extract is good for performance can by carefully moderating parameters.
