摘要
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 % NaHCO3 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 isotherm is followed.
