“…The use of corrosion inhibitors is one of the most effective measures for protecting carbon steel surfaces against corrosion in CO 2 environments (Abd El-Lateef et al, 2013a,b,c). Most of the well-known corrosion inhibitors are organic compounds containing nitrogen, sulfur, or oxygen atoms (Cheng et al, 1999;Prabhu, Venkatesha, Shanbhag, Kulkarni, & Kalkhambkar, 2008;Samide, Bibicu, Rogalski, & Preda, 2004;Verma, Quraishi, & Ebenso, 2013;Wang, 2001).
