The effect of BIMGCS12-3 as the inhibitor for the corrosion of mild steel in 1M vitriolic acid

摘要：

　　The effect of propanediyl-α,ω-bis-(N-dodecyl benzimidazole ammonium bromide),(abbreviated as BIMGCS12-3),as the inhibitor for the corrosion of mild steel in 1 M vitriolic acid was tested.It was found by Tafel polarization curves that BIMGCS12-3 as mixed type inhibitor adsorbed on the mild steel surface forming a protecting film.EIS measurements were carried out in a frequency range of 100kHz to 10mHz with amplitude of 5mV using ac signals at open circuit potential.Changes in impedance parameters (charge transfer resistance.Rct,and double layer capacitance,Cdl) were indicative of the feasibility of BIMGCS12-3 as excellent mild steel corrosion inhibitor in 1 M sulfuric acid.Surface morphology of the specimens was examined by SEM.
