Abstract Corrosion rate data are presented for low carbon steel in (1) a combination of sulfur dioxide, water vapor and air, and (2) aqueous solutions of sulfurous acid in the absence of air, at ordinary temperature. Information as to the nature of the corrosion products is presented and it is shown that this depends on the place in which the corrosion takes place to an important extent.

Corrosion inhibition potential of Eichhornia crassipes extract on low carbon steel in 1 M sulphuric acid solution was investigated using gravimetric method and corrosion rate. The experiment was carried out for 3 hours at different concentration of Eichhornia crassipes extract and temperatures of 26.6°C, 40°C and 60°C. Arrhenius and improved Arrhenius equations were used to determine the thermodynamics properties of the reaction while the nature of the reaction was proposed by adsorption isotherms. The results showed that corrosion rate decreased in the presence of the extract except in 60oC. Inhibition efficiency also increased with extract concentration with the highest (82%) occurring at room temperature and 5% concentration. Inhibition efficiency decreased with increase in temperature with almost no inhibition at 60oC, this is associated with physisorption. Activation energy () and activation enthalpy () both had positive values and they increased in the presence of Eichhornia crassipes extract, those for inhibited solution were higher than those for uninhibited solution, these can also be attributed to physisorption. Inhibition  reaction obeyed Langmuir adsorption isotherm. Gibbs free energy () calculated for the reaction is -8.509 to -11.767 kJ mol-1.
