thiosulfates การใช้

• Thiosulfates are particularly aggressive species and are formed by partial oxidation of pyrite, or partial reduction of sulfate.
• They can grow on other partially oxidized sulfur compounds ( e . g . thiosulfates, thionates, polysulfides, sulfites ).
• Besides chlorides, other anions implicated in pitting include thiosulfates ( S 2 O 3 2 & minus; ), fluorides and iodides.
• Thiosulfates are a concern for corrosion in many industries : sulfide ores processing, oil wells and pipelines transporting soured oils, Kraft paper production plants, photographic industry, methionine and lysine factories.
