Abstract
The inhibition action and adsorption behavior of an environment-friendly inhibitor polyepoxysuccinic acid (PESA) on copper in aqueous NaCl (0.02%) solution was investigated by means of electrochemical techniques. The results indicated that the best inhibition efficiency of PESA was 69.5% with the concentration of 12 mg/L at 20 . The adsorption of PASP prevented Cu from being corroded. The adsorption behavior of PASP followed Langmuir isotherm, it was spontaneous, and belonged to chemical adsorption.
