Abstract  Two pyrazolone compounds, POTAS and PDTAS, were synthesized and their inhibition action and adsorption behavior on copper in aqueous NaHCO3 (mass fraction 5%) solution were investigated by means of mass loss and electrochemical techniques. It was showed that the two compounds had good corrosion inhibition for copper in NaHCO3 solution. The inhibition efficiency of the two compounds was found to decrease as follows: POTAS>PDTAS. Both POTAS and PDTAS were mixed-type inhibitors. The results of experiment revealed that the adsorption on copper surface was monolayer adsorption. The adsorption processes were exothermic reaction and belong to physical absorption.
