Study~Testing of Guava Leaf Extract and Papaya as Corrosion Inhibitor
Corrosion Inhibitors that are Environmentally Friendly and Economical.
Current research is corrosion, corrosion is a process of corrosion that occurs in iron, steel plate or machine, corrosion can occur because of moisture or steam. Corrosion or corrosion can be prevented or overcome by the addition of inhibitors, inhibitors used in the form of chemicals or natural materials (plants) but on this occasion I use inhibitors of plants because it is easy to obtain and environmentally friendly such as papaya leaf extract and guava extract.
The first process that is done is sanding iron plate. Then the sanding iron plate was weighed using an analytical scale to see the weight of its steel plate. Then the steel plate that has been weighed in the test by using a corrosive solution of HCL 0.5M and aquadest as much as 13liter. The HCL and aquadest solution were diluted as much as 13 liters and then incorporated into the jeringene.
The steel plate is then conveyed to the hanging wire to be immersed into the filled glass. Corrosive solution, no corrosive solution Without inhibitor and there is also a corrosive solution with the addition of inhibitor. Then the steel plate that has been soaked for 3hari to see the results achieved, because the purpose is used This solution to prevent the occurrence of corrosion on the plate.
The resulting inhibitor can be used as a reference to reduce the corrosion rate of carbon steel in a 0.5 M HCl environment
The resulting inhibitor is more economical, environmentally friendly, and safe to use and has the ability to either inhibit corrosion of a more dangerous chemical substitute.
