چکیده
|
The inhibition performances of nafcillin (iii),methicillin (ii) and penicillin g (i) on the corrosion of copper in hcl was studied and tested by weight loss,tafel polarization,sem,uv-vis spectrophotometry,molecular dynamics method and quantum chemical calculations. polarization curves indicated that the studied inhibitors act as mixed-type inhibitors. the values of inhibition efficiency and surface coverage were found to follow the order: blank methicillin (ii)> penicillin g (i),which confirmed that nafcillin has the strongest interaction with the metal surface. the obtained results from experimental and theoretical methods were in reasonable agreement. © 2017,iran university of science and technology. all rights reserved.
