Corrosion Inhibition of Carbon-Steel in (0.1M) HCl and NaCl using Sulfasalazine Drug

Adnan Sultan Abdul Nabi, Mouayed Yousif Kadhum, Alaa Ali Hussain

Sulfasalazine drug (SS) was identified by CHN, FTIR, 1HNMR and 13CNMR techniques. The effect of Sulfasalazine on the dissolution of C-steel in 0.1M HCl and 0.1M NaCl solution was studied using weight loss and galvanostatic polarization techniques. The inhibition efficiency of inhibitor increases with concentration to attain (93.42 %) in HCl and (79.31 %) in NaCl at concentration 110^ (-2) M, and standing time for 240 min at 25C. Temperature effect on the corrosion behavior was studied at temperature range from 25-45C, the results showed that inhibition efficiency decreased with increasing temperature to attain (70.14 %) in HCl and (50.92 %) in NaCl concentration 110^ (-2) M for both, at 45C and with standing time equal to 240 min. The effect of temperature on the rate of corrosion in the absence and presence of Sulfasalazine (SS) drug was also studied. The activation energy was calculated and discussed. The polarization curves revealed that the studied inhibitor represent a mixed type inhibitors. Adsorption of inhibitor was isotherm physisorption type.
