Abstract:	Despite extensive research over the past several decades, effective inhibition of mild steel (MS) corrosion is still a challenging problem. Potassium ethyl xanthogenate (KEX) is well known in the mining industry for extracting various ores. Its applications in other fields, such as in the synthesis of unsymmetrical compounds, as surfactants, and in microbiology, have also been documented. However, surprisingly, its use in the prevention of corrosion of MS in acidic media has so far not been explored. We discovered that KEX is highly effective in preventing MS corrosion in acidic media. The interaction of KEX with MS was investigated using conventional electrochemical techniques, SEM, and EDX spectroscopy. Corrosion inhibition efficiency was 92.4% in 1M HCl and 98.1% in 1M H2SO4. Experimental results were validated with theoretical and computational studies.
