Data and statistical analysis on the corrosion inhibition effect of four organic chemical compounds on carbon steel in dilute H2SO4 and HCl solutions

Data on the protection performance of n,n dimethylaminoethanol (DAE), 2-amino-5-ethyl-1,2,3-thiadiazole (TDZ), p-phenylenediamine (PDM) and diphenylthiourea (THO) mild steel in 0.5M H2SO4 HCl solution were studied. The compounds more effective solution. N, n displayed most at all concentrations studied with optimal value 97.901% 90.671% HCl. P- phenylenediamine compound exhibited weak both acids values 69.995% 1% concentration (H2SO4) 83.131% 0.5% highest TDZ inhibition efficiency is 80.671% 95.796% Inhibition varied differentially In H2SO4, increased increase concentration. Similar observation occurred for THO compound. At 0.25% above 90%. HCl, are 0.5%, 0.75% observed generally above. Statistical data showed standard deviation, mean margin error compounds. Analysis through (ANOVA) was performed to assess statistical relevance exposure time inhibitor (sources variation) organic fluids acids.
