Durio Zibethinus Extract Performance as Corrosion Inhibitor in Simulated Seawater

Abstract

Many natural resources from agricultural waste are used as inhibitors, one of which is Durio zibethinus. The systematization of the electrochemical experiment and morphology characterization were performed to analyse the corrosion inhibitor characteristics. The adsorption was calculated to help further understand the inhibition mechanism. The electrochemical results showed that the inhibitor extract acted as a cathodic type, with inhibition efficiency up to 75.05% using the method of PDP and 64.69% using the method of EIS. Based on the investigation of corrosion inhibitors, the adsorption isotherm agreed with the experimental results. The EIS data confirmed the chemical reaction and physical adsorption processes of the multi-component corrosion of DZE inhibitor. The results revealed the potential use of DZE inhibitors in applications such as desalination plants. Further, the improvement in performance was conducted through the use of synergy effects.
