用失重法和电化学方法研究了5-丙基-2-氨基-1,3,4-噻二唑 (APT)和5-异丙基-2-氨基-1,3,4-噻二唑(AIT)对Cu在3%NaHCO3溶液中的缓蚀性能和吸附行 为.结果表明,在3%NaHCO3溶液中两种化合物对Cu均有较好的缓蚀性能,并且前者的缓蚀性 能比后者的好. 两种化合物在Cu表面上的吸附过程为放热过程,其在Cu表面上的吸附行为服 从Langmuir吸附等温式,属化学吸附.
2-amino-5-propyl-1,3,4-thiodiazole and 2-amino-5 -isopropyl-1,3,4-thiodiazole inhibition behavior on H62 copper in 3%NaHCO3 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 HCO3 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.
