Abstract 2-amino-5-propyl-1,3,4-thiodiazole and 2-amino-5 -isopropyl-1,3,4-thiodiazole inhibition behavior on H62 copper in 3%NaHCO3 solution is investigated by means of weight loss and electrochemical methods.It is shown that two inhibitors have good inhibition performance for copper in 3%Na HCO3 solution.And 2-amino-5-propyl-1,3,4-thiodiazole’s inhibition efficiency is better than 2-amino-5-isopropyl-1,3,4-thiodiazole’s.The adsorption processes are exothermic reaction and belong to the chemical adsorptions.The Langmuir iso therm is followed.
