【Abstract】 Corrosion behavior of HSn70-1+As,B30 and carbon steel in sulfide containing water was studied by mass-loss and surface analysis.Their corrosion was accelerated by sulfide in water.HSn70-1+As was suffered from dezincification,and carbon steel corroded uniformly.The mechanism and effectiveness of removing S 2- by industrial ferrous sulfate and polymeric ferric sulfate were studied with a laboratory test set.The optimal addition of industrial ferrous sulfate and polymeric ferric sulfate was acquired.Based on the experimental results,a prototype dynamic test further proved that industrial ferrous sulfate showed a good efficiency with fast rate in removing S 2-.更多还原
