... This study examined the sediment quality of the eastern Seto Inland Sea in terms of the fluctuation of the population of sand lance, based on the investigation results. The result showed that the sulfide content of sandy sediments deviates widely with ignition loss, and that “the modified...

... Most cities, counties, and sanitary districts have used concrete pipe for sewer construction during the past 100 years. Many of these pipelines under certain site conditions have been corroded by sulfuric acid formed from sulfide gas. Despite this track record, many design engineers are still...

... Films formed on copper exposed to various sulfur-bearing environments were analyzed by XPS and electrochemical reduction to study the formation of copper sulfide. The S-2p photoelectron band showed the presence of copper sulfide in the film in addition to oxysulfur species. Coulometric reduction...

... vessels or small cells contained in anaerobic jars. The problem with such tests is that they give much lower rates of corrosion than those frequently experienced in the field. This is almost inevitable, as the total quantity of hydrogen sulfide produced is small compared with the surface area of the test...

... by reinoculation or the addition of biocides) over a long period. Metal swarf is added to the apparatus and its corrosion can be rated visually. The corrosiveness of the fluid can also be determined at intervals using the standard metal chip test. sulfide metal-working fluids preservatives biocides...
