Green Corrosion Inhibitor

A green corrosion inhibitor similar to polyepoxysuccinic acid is synthesized by using maleic anhydride and sodium allylsulfonate as raw material. The molecular structure is characterized by IR spectra. The efficiency of an environmental-friendly corrosion inhibitor for carbon steel in sea water is researched through method of weight loss. This new corrosion inhibitor is a mixture of multipolymer, Zn2+ and HEDP. The efficiency of the corrosion inhibitor for carbon steel in the sea water is 97.68%, when the concentration of multipolymer is 50mg/L, Zn2+ is 4mg/L, HEDP is 10mg/L. The surface of carbon steel is investigated by electron microscopy after the experiment of corrosion, and the mechanism of corrosion inhibitor is discussed.

The effect of aqueous extract of UAE Neem (Azadirachta Indica) on the corrosion inhibition of carbon steel in 1.0 M HCl solution was investigated electrochemically, and by weight-loss experiments at temperatures ranging from 303 to 343 K. The percentage inhibition increased with the increase of the concentration of the inhibitor. At a concentration of 2.0 g/L, the percentage inhibition reached about 87% at room temperature and 80% at 303 K. The percentage inhibition decreased with the increase of temperature. The thermodynamic parameters for the adsorption of this inhibitor on the metal surface were calculated using the Temkin adsorption isotherm. The aqueous Neem leaves extract was found to be an excellent potential corrosion inhibitor because of the high content of tannin content as well as the presence of a series of complex triterpene glycosides.
