“…The synergistic effect of halides has been observed to increase in the order of Clˉ < Brˉ < Iˉ. Because of its large size and ease of polarization, iodide (Iˉ) shows the highest synergistic effect [9].…”

The corrosion inhibition of rice husk extract for bio-corrosion in mild steel in 1 M of H2SO4 solution and the effect of adding potassium iodide were investigated using the weight-loss method with a variable solution temperature and various bio-inhibitor concentrations. The addition of potassium iodide can significantly increase the efficiency of rice husk extract. The highest efficiency is 95.89% at 1,250 ppm of inhibitor concentration at a temperature of 313 K. The inhibition efficiency of rice husk extract is synergistically increased with the addition of potassium iodide. The characteristics of the adsorption inhibitors were assessed using the Langmuir isotherm adsorption approach at all studied concentrations and temperatures. The synergy of rice husk extract and potassium iodide was examined using thermodynamic and kinetic parameters.because it has the advantage of being biodegradable and does not contain heavy metals or other toxic compounds.Rice husk is considered one of the most important agricultural wastes, and a great amount of research has been conducted on its use in various fields. It has a high silica content, which is a good advantage, especially for bio-corrosion inhibitors [3]. Rice husk extract (RHE) has the potential to be developed into a bio-corrosion inhibitor [4,5] and contains amorphous silica, which is safe and environmentally friendly.Recently, researchers have been paying more attention to mixed inhibitors because of their synergistic effects. The effect of the inhibitor mixture is better than the single inhibitor effect. Further, several authors have reported that halide (Iˉ) ions, which are known to stimulate and inhibit corrosion in acid solutions, can provide their own effective protection or can be com-

The corrosion inhibition efficiency of Triton X 100 in controlling surgical carbon steel instrument corrosion in well water has been analysed by weight loss method. Mechanistic aspects of corrosion inhibition efficiency have been studied by Polarization and AC impedance measurements. The formulation consisting of 200 ppm of Triton X 100 and 50 ppm of Zn 2+ provides 84 % corrosion inhibition efficiency. A synergistic effect exists between the surfactant Triton X 100 and Zn 2+ . Polarization study confirms that Triton X 100 -Zn 2+ system functions as a mixed type of inhibitor. AC impedance spectra shows that a protective film is formed on the carbon steel surface. Cyclic voltammetry data confirms the stability of the protective film in presence of 3.5% NaCl solution. FTIR spectra reveals that the protective film consists of Triton X 100-Fe 2+ complex and Zn(OH)2. SEM, EDX, data indicate the possibility of formation of protective layer on the metal surface. FTIR spectra confirms the formation of protective film on the metal surface. AFM study reveals the surface morphology and gives the information of the thickness of the protective film. Contact angle measurement confirms the hydrophobic nature of the protective film formed on the carbon steel surface.
