“…Mobin [37] studied the corrosion inhibition of mild steel in sulphuric acid solution in presence of starch (polysaccharide) using weight loss and potentiodynamic polarization measurements in the temperature range of o C. Starch moderately inhibits the corrosion of mild steel in the studied medium. The inhibitor was modified by adding a very small concentration of sodium dodecyl sulfate and cetyltrimethyl ammonium bromide and the effect of the addition on the corrosion inhibition behavior of starch were also examined.…”

“…Temperature was found to have profound effect on the inhibition efficiency; a severe decline from 91% at 10 o C to 31% at 40 o C with the same concentration of pectin was reported. Hassan and Zaafarany [25] studied the corrosion inhibition of aluminum (Al) in hydrochloric acid by anionic polyelectrolyte pectates as a [35]; [37] Carboxymethyl Cellulose H2SO4, HCl Mild steel [16,22,29] Gum Arabic HCl Mild steel [32] Hydroxy-ethyl cellulose HCl Mild steel; Aluminium [30]; [30] Gellan gum HCl Cast iron [31] water-soluble natural polymer polysaccharide using gasometric and weight loss methods. Results of the investigation revealed that the inhibition efficiency offered by inhibitor increased with increase in the concentration but decreased with rise in temperature.…”

Abstract:The use of corrosion inhibitors is the one the most economical and practical means of controlling metallic corrosion in different corrosive media. Interest on the use of eco-friendly organic compounds as corrosion inhibitors has extended to the use of polymers to inhibit metallic corrosion. The use of polymers as corrosion inhibitors has attracted attention and has gained wide acceptance in recent times. This has been attributed to a number of factors namely: (i) they are low cost and stable to metallic materials in acid media, (ii) they possess multiple adsorption sites, (iii) through their functional groups, they form complexes with metal ions and on the metal surface these complexes occupy a large area, thereby blanketing the surface and protecting the metal from corrosive agents present in the solution. A number of synthetic and natural polymers as metallic corrosion inhibitors have been investigated and reported. As an update to previous review work on the use of polymers as corrosion inhibitors, the present review presents most of the contributions made to the literature on the use of polymers as corrosion inhibitors of diverse metals in different corrosive media in the last four (2010)(2011)(2012)(2013) years.

“…The surfactants have a remarkable ability of influencing the surfaces and interfaces. They have been used as corrosion inhibitors either alone or in combination with other compounds to improve their performance as inhibitors [17][18][19][20][21] . The surfactant molecules possess strong adsorption ability to the metallic surfaces.…”

Gemini surfactants, butanediyl 1,4-bis(dimethyl cetylammonium bromide), pentanediyl 1,5 -bis (dimethyl cetylammonium bromide) and hexanediyl 1,6 -bis (dimethyl cetylammonium bromide) from Alkanediyl-α, ω-bis (dimethyl cetylammonium bromide) series were synthesized in laboratory and were characterized by using Nuclear Magnetic Resonance (NMR) spectroscopy. The surfactants were tested as corrosion inhibitors for mild steel in 20% formic acid. The influence of surfactants on mild steel corrosion inhibition was investigated by measuring the corrosion rate of mild steel in their absence and presence by weight loss measurements, solvent analysis of iron ions into the test solution and potentiodynamic polarization measurements. The surface morphology of the corroded steel samples in presence and absence of surfactants was evaluated by using Scanning Electron Microscopy (SEM). The synthesized gemini surfactants performed as excellent corrosion inhibitor, the inhibition efficiency (IE) being in the range of 76.66-97.41%. The IE of surfactants is slightly affected by the spacer length. The IE increased with increase in surfactant concentration and temperature. The adsorption of gemini surfactants on the steel surface was found to obey Langmuir adsorption isotherm. The results of the potentiodynamic polarization studies are consistent with the results of weight loss studies.

“…Moreover, the GTS molecules that adsorbed on the surface of the metal substrate interact between the lone pairs of electrons of the oxygen atom and the carbon steel surface, which supported the adsorption process. So, the presence of d π-vacant orbital of low energy in the iron atom also contributed to the adsorption process [27]. Table 2.…”

This research was focused on discovering the utilization of Dioscorea hispida (gadong tuber) starch as a potential green corrosion inhibitor for SAE 1045 carbon steel in 0.6 M NaCl media. Raw starch from gadong tubers was obtained through the extraction and precipitation process prior to drying in producing fresh starch powder. The insoluble starch powder was then dissolved in 90% dimethyl sulfoxide (DMSO) solvent and was ready for corrosion inhibitor testing. The extraction of starch powder was analyzed using Fourier Transform Infrared Spectroscopy (FTIR) to identify the presence of functional groups that may contribute to the inhibition of the carbon steel sample. The inhibitive performance of gadong tuber starch (GTS) as a green corrosion inhibitor was studied by weight loss measurement and potentiodynamic polarization in a corrosive medium using 0.6 M sodium chloride (NaCl) solution. Effect of GTS concentration on corrosion behavior was investigated. Based on the findings, 1500 ppm of GTS demonstrated the highest corrosion inhibition performance as the corrosion rate of carbon steel immersed in plain 0.6 M NaCl was reduced from 0.131 to 0.018 mm/year, which is up to 86.3 IE% of inhibition efficiency in the presence of the green corrosion inhibitor. According to potentiodynamic polarization analysis, corrosion current density (I corr ) was also decreased from 1.13 × 10 −5 to 1.55 × 10 −6 mA/cm −2 .
