Abstract

In the mining industry (petroleum) organic acids that have low molecular weight such as formic acid and acetic acid when mixed with water will become a corrosive medium on the inside of the iron used in production. The use of inhibitors is the cheapest, easiest, most effective, and environmentally friendly corrosion control technique so that it is widely applied in various industrial fields, such as the petroleum mining industry. Mango peel extract was obtained through the extraction process using maceration methods identified by the phytochemical test and FTIR on extracts obtained. The media used in NaCl 1% electrolyte solution. The inhibition activity of mango peel extract increased with increasing inhibition concentration. In the compound of polar mango peel extract obtained optimum inhibition efficiency at a concentration of 48 ppm was 62.7572%. Whereas in the semi polar mango peel extract compound the optimum inhibition efficiency was obtained at a concentration of 40 ppm with inhibition efficiency of 90.0807%. Based on the results of SEM, Iron without inhibitors and not by immersion in an electrolyte solution such as slabs, iron with immersion in an electrolyte solutions only such as corroded and iron with the addition of inhibitors and immersion in an electrolyte solutions seen to protect the iron from corrosive.
