Abstract

In research carried out measurements of weight loss with API 5L grade B material in a solution of HCl 1 M. Extract Myrmecodia Pendans is used as a corrosion inhibitor. Immersion time was 2 hours, while the temperature variations used are 30, 40 and 50°C. Extracts of the ants 100-500 mg / L (multiples of 100 mg / L). In this study will also be analyzed with some models of adsorption mechanisms, including the Langmuir, Freundlich, and Temkin. This study aimed to determine the appropriate method of adsorption isotherms on each system. Adsorption equations of the model will be obtained values of free energy of a system. With the known value of free energy, it can be seen whether the adsorption occurs in physics or chemistry. This related to the surface protective layer formed on the surface absorption extract Myrmecodia Pendans. The results showed that the adsorption followed the Langmuir adsorption method at 30 and 40°C, while the temperature of 50°C followed Freundlich adsorption methods.
