Metals are protected from corrosion by using inhibitors. To replace the environmentally hazardous inorganic and organic chemicals, various plant extracts were tested as green inhibitors. In this PPPP, inhibition of corrosion of various types of brass, medium and green inhibitors have been reviewed. The green inhibitors are eco-friendly, cheap and easily available. Protective films on metal surface is formed by adsorption of polar atoms present in inhibitors onto the metal surface. Inhibition efficiency of inhibitors depends on their chemical structure and properties. Adsorptions of these ingredients on metal surface obey various adsorption isotherms. Corrosion of metals and its inhibition was analyzed by weight loss method with different time and temperatures. Corrosion study was carried out by Open Circuit Potential (OCP), Galvanostatic polarization and Electrochemical Impedance Spectra (EIS) methods. The protective films have been analyzed by various techniques such as X-ray Diffraction spectroscopy (XRD), Energy Dispersive X-ray Spectroscopy (EDX), Scanning Electron Microscope (SEM), UV-Visible spectra, AFM and Fourier Transform Infrared (FTIR) spectroscopy. The present review PPPP is an overview of works published on protection of brass metal from corrosion by using green inhibitors.
