Popis
Shrnutí:Electrochemical and corrosion behavior of mild steel in neutral media containing hydrogen sulfide has been investigated by weight-loss and electrochemical methods and protective effect of industrial compositions SONKOR has been determined. It has been shown that in 3%  NaCl compositions SONKOR have weak protective effect but it increases greatly in presence of hydrogen sulfide in the solution. At concentration of H2S = 0,6 gram per liter maximal protective effect has SONKOR 9801 (85,57%) and SONKOR 9920А (81,97%). Inhibitors SONKOR 9021С (70,82%), 9510А(73,11%) and 9701(67,87%) show less protective effect.
