PENGHAMBATAN LAJU KOROSI DENGAN MEMANFAATKAN EKSTRAK DAUN MANGGA (Mangifera indica L) SEBAGAI INHIBITOR KOROSI
Daftar Isi:
- Corrosion known as corrosion is an event of damage or loss of quality of a metal that is caused by a reaction to the environment. Extract Mango Leaf (Mangifera indica L) is an organic material that can be used as an inhibitor to reduce the rate of corrosion of iron in hydrochloric acid environment. The use of extracts of Mango Leaf (Mangifera indica L) is expected to be inhibitors that are safe, environmentally friendly and biodegrable and be able to reduce the use of inhibitors of the synthesis. Inhibitors of Extract Mango Leaf (Mangifera indica L) was selected as an organic inhibitor because it contains antioxidants that can inhibit the corrosion rate as anthocyanin. Weight loss method is used to test the effectiveness of extracts of Mango Leaf (Mangifera indica L) as a corrosion inhibitor in a metal plate measuring 4 cm x 2 cm x 0.20 cm with a variation of inhibitor concentrations (0 ppm, 150 ppm, 300 ppm) and long soaking time (48 hours, 96 hours, 144 hours, 196 hours and 240 hours). The results showed that the use of extracts Mango Leaf (Mangifera indica L) is most effective when used in corrosive environments HCl 1% solution at a concentration of 300 ppm with a soaking time of 48 hours with an efficiency of 16,725%.
